I calculated the antenna using AutoEZ invoking EZNEC v6.0.9.  Transmission line 
calculations using TLDetails (previously referenced) and/or if you have Excel, 
LineLoss.xls.  All except for EZNEC available from AC6LA.com.  Dan has a wealth 
of information on his site, all of it fabulous documented.

Some editions of the ARRL Antenna Book had material on "Highly Reactive Loads", 
shamelessly stolen from my correspondence with ARRL that also presented some of 
this.

Some of us deliberately operate with the roofing and DSP at the same
bandwidth, and with some care to get the skirts coincide. This provides the
maximum possible drop at the edges, quite useful in a crowded contest. I
want to hear equally well in a specific bandwidth, and then I want the
selectivity skirts to drop as close to straight down as possible.

Generally not needed for casual operation, and I will operate the casual
QSO's sometimes with the DSP bandwidth at 700 or 800 Hz just because it
"sounds better". and 1.8 kHz (the contesting SSB width) roofer behind it.
Get people too close and I just tighten the width back up until I don't
hear them any more. Generally people seem to give you 1 kHz spacing for
casual.

As others have noted, the K3 is not like older radios -- it gets its IF 
selectivity from DSP. You can set it anywhere you want. The plug-in 
filters are roofing filters -- they protect the DSP from getting blown 
away by big signals close to your frequency. You need them in contests 
and in DX pileups, but that's all. I use narrow CW filters like K2AV 
described for contesting. For everything else, the IF filtering provided 
by DSP is all you need.

Hi Andy,

several replies giving you an ideas over here.
Refer to Jim, K9YC...it is short and clear.

I am recommending you to simply stay calm.
Turn your radio ON, sit and play...
Use it daily in different situation for few months
then you will be more familiar with radio and
all functions behavior and you will have better idea
what you really need.

Good luck and enjoy your K3!

Wireman 553 uses a 19 strand Copper Clad Steal (CCS) conductor which
results with very thin copper cladding. 553 is skin saturated at about
15 MHz. The loss at 1.8 MHz is approximately 0.21 dB per 100 feet.

http://www.kn5l.net/wm553/

Using EZNEC and SimSmith for the antenna below results with 13.8 dB
transmission line loss. Slightly greater loss then Wes' calculations.

While without reference to quantities I certainly agree with the sentiment,
but to be focused on a night light level power is kind of like swatting at
gnats while pidgeons are flying around in the kitchen.

Does your attic insulation need replacing. Are all of the light fixtures in
your house converted to LED. Are your refrigerators made in the current
decade. Are all of your windows gas-filled double pane. Are your water
heater and all the hot water piping in your house insulated. The list of
things that would bury that 6 watts by a couple of orders of magnitude is
quite long.

Then there is this other thing specific to CPU based equipment. And that is
maintaining signal states relative to other equipment. They get confused
when things go cold off and aren't brought back on in a particular
sequence.

It was always fun when the PC folks at SAS (which is buried in PCs) had to
take down a thousand or so functionally shared PCs for maintenance or
something. They had to be taken off in sequence and brought back in service
with a very complex and specifically ordered startup. Every now and then
that group had to work all hands on deck 48 hour weekends and took naps on
cots put out for the purpose. Those PCs were kept on their own AC mains
with a honking monster UPS that would power my house for weeks off the
grid. Power blips taking down a couple floors of PCs could put a building
full of very high paid advanced programmer types sitting on their hands for
a day or worse. They figured that out early and spent the money.

Your Elecraft gear has some related if not so killer issues on cold starts
that nevertheless result in tech support calls. Think Big E just trying to
keep the noise and confusion down on the TS lines, with a method that has
become pretty much standard practice.

Seems to me it's been a long time since TVs had batteries in them unless it
was a portable intended to be operated off mains. Paying for a service call
to replace a battery gone bad was drummed out long time back.

If you have a PC in the shack, do you do a shutdown when you leave? Or
leave it on to get OS and virus security updates and email?  Check the
power draw on that.

I'm trying to convince the wife to replace our 23 year old kitchen
refrigerator that still works perfectly.

I wish that my KPA's off state power draw was the prime offender at my
house :>).

Message-ID: <CA+vZ_+L5nG-vnSgdMgRUaO2k1382EJKMRkx79xT-gCr-M8fieA@mail.gmail.com>

Just received my KX2 and I'm very pleased with it, although fitting the ATU
was a challenge, even after having read the updated information on it!

Anyway, I believe all is well but there is something that I don't
understand.  If the KX2 has been off for a while, when I turn it on I get
some random parts of characters, mainly along the bottom half of the
display.  They remain there for about 3 seconds until the display
illumination comes on and the rest of the display disappears.  This is
absolutely no big deal unless it's a sign of some issue somewhere that has
yet to rear its ugly head!

Running latest (2.69) firmware.  I have a K3 and KX3 and have never noticed
this behaviour with them.

Desk top PC can eat over 400 watts of power just sitting there.
When finished, I always put mine in "standby" or "sleep" mode which drops
the power usage to a few watts.
I verified these readings with one of those handy little "Kill-O-Watt" power
line devices.

Subject: [Elecraft] Many thanks
Message-ID: <6221ef0e-ea32-1996-4ec6-891f4dc9d6f5@gmail.com>

Dear folks at Elecraft and on the list;

I have been enjoying Elecraft products for many years, starting with a 
K1, then a K2, then a KX2... followed by my current K3, KX3, and KX2.

I use the K3 as my mainradio in the shack. It is fairly loaded with the 
second receiver and nice filters and supplemented by a P3 and a KPA500 
and KAT500.  They feed a 3 element Quad up 75 feet on 20 - 6 meter, and 
dipoles for 160 - 30 meters.

I use the KX3 as a secondary station in my library with different 
antennas and a KXP3 and KXPA100.

I use the KX2 as my portable station when I am out camping or on a picnic.

Over the years, I have come to anticipate the new releases from Elecraft 
eagerly.

I just wanted to thank Elecraft for their top notch designs and customer 
support which I have benefited from more than once, and to thank the 
list for their support as well; they have contributed significantly to a 
hobby I have enjoyed now for some 59 years and hope to for a few more years.

best 72 for the QRPers, & 73 for the QROers out there.

--W5SV, Dave

I have a 1k filter.  Does it make much difference.  I have no clue 
really.  Would I be better served with an FM filter?  maybe .  My main 
receiver has 2.8. 1.8. 1.0 400 and 250 or 200 filters. I do ssb contest 
and travel to DX locations from time to time. The SSB filters are 
essential.  For CW I honestly think that the 400 is fine for most.  I 
dislike the sound when I really crank the skirts down on CW but 
sometimes you must so it is nice to have it.

If you plan to do diversity receivers you need the same filters in each 
one and they need to be "matched" as close as possible to get the best 
results.

2.7 and 400 and and FM filter if you want fm and or AM would be fine for 
many.

Hi Stephen,

This is completely normal. Sometimes the segments will be randomized, sometimes not. We initialize the LCD after doing a checksum and power-up status checks. 

If you watch carefully you may discover meaningful patterns in the seemingly scrambled segments. This can be a therapeutic family activity and a welcome distraction from obsessing over politics, dark matter, and related issues.

Jim,

If you don't object, I'd like to save this and forward to people as 
arguments develop on these subjects.

  I wish you had touched on '4:1 baluns'.  Except for this group, so 
many people I talk to think a balun should be 4:1, even in their 
tuners.  I think it is DX Engineering that addresses this well.

That raises an interesting question.
 
Looking at Rob's numbers (assuming I've read the chart footnotes correctly) 
 he's done the close in numbers for the KX3 with and without the roofing  
filter.
 
But the close in numbers for K3S numbers were only done with the cw  
roofing filters.
 
Is there with/without roofing filter data available for the K3S I  missed? 
 
I realize the proof is in the performance, but still, inquiring minds and  
all that.....
 
Cheers Scott ka9p

Leave it to an environmentalist (I'll spare the engineers) to advocate 
the spending of thousands of dollars in redesigning something that can 
be fixed with a quick trip to a local hardware store for a $25 (or less) 
master kill-switch.

Practical side only.

Assume you use a random wire antenna. AT in K2 or KX3 will not match all
bands directly. It will match with BL1 or BL2 in 4:1 mode. This is because:
1. After transformation, the impedance is more manageable to KAT2 or KXAT3.
2. Loss in balun. Mainly on lower bands with short antennas. 

Whenever I have space for BL1, I use it. It is no brainer as I prefer the
match than no match and balun overheat than AT overheat. Heating occurs
mainly at bands were the wire is too short.  

New transformers can have extremely low loss. A 64:1 transformer used for
40-10 or 80-10 endfeds at myantennas.com is just warm at a KW level.

Am I missing something?

Didn't it take power to to charge that supercap or backup battery?

Is there really a difference between drawing a tiny bit of mains power 
when "off" and drawing a tiny bit of mains power to maintain these when 
"on?"

Too often, it's easier to move a problem around than to actually solve it.

"Incredibly wasteful" - Seems like a little bit of an overstatement.

That's only 4.968 Kilowatt-Hours a month assuming it is idling 24/7 for
30 days.

For me, that'd be about $0.49 in electricity.  At $0.22 a KW-Hr, it'd
still be under a buck per month.

If this is still "incredibly wasteful" then you need to check every
other appliance and electrical device in your house, because most of
them are likely consuming "incredible" amounts of electricity when they
are "OFF".

If you really must avoid consuming this 5 KWHr (it won't be that much
"waste" because you have to subtract the actual usage time), then you
can place an accessible switch like a properly sized multiplug inline
with the KPA500, et al. to switch off the power altogether AFTER you
shut it down at the front panel.

Have a great day...

73,

Thanks...  and if I missed a response from the OP, thank as well.

Well then...  that seems to vindicate my desire to avoid CCS wire and
"overengineer" with the use of larger wire diameters.
And it clues me in to pay attention to every single detail when
designing a transmission line system.

Thanks again...

Dave,

Perhaps you want to turn on your amp manually each time. But what you 
may have missed is that 7 watts is doing more than just detecting 
whether the power switch on the front is used or not. When the KPA500 is 
"off" the RS-232 connection on the back is still live, and there is a 
processor in the KPA500 that is monitoring that connection. You can 
remotely turn on the KPA500 using the KPA utility.  For those whose 
KPA500's are in a remote location, or just in an inconvenient location 
(i.e. not adjacent or within easy reach of your operating position), 
this is a very nice feature. It would be more than just the "power 
supply system" that would need to be redesigned.

73,

This may not always be possible.

Copper-clad steel exists because it's stronger than copper.  Wind, ice, 
or simply a long span can exceed the strength of copper, and then you 
don't have an antenna at all.

"Over-engineering" by making the wire bigger also makes it heaver and 
gives it a larger cross section (more windage).

I guess you could take your large diameter copper and wrap it around 
something else to hold it up, but that's basically the idea behind 
copper clad steel.

To me, the earlier post means that not all copper-clad wire is suitable 
for all antennas -- with #553 as an example.

Dear folks at Elecraft and on the list;

I have been enjoying Elecraft products for many years, starting with a 
K1, then a K2, then a KX2... followed by my current K3, KX3, and KX2.

I use the K3 as my mainradio in the shack. It is fairly loaded with the 
second receiver and nice filters and supplemented by a P3 and a KPA500 
and KAT500.? They feed a 3 element Quad up 75 feet on 20 - 6 meter, and 
dipoles for 160 - 30 meters.

I use the KX3 as a secondary station in my library with different 
antennas and a KXP3 and KXPA100.

I use the KX2 as my portable station when I am out camping or on a picnic.

Over the years, I have come to anticipate the new releases from Elecraft 
eagerly.

I just wanted to thank Elecraft for their top notch designs and customer 
support which I have benefited from more than once, and to thank the 
list for their support as well; they have contributed significantly to a 
hobby I have enjoyed now for some 59 years and hope to for a few more years.

best 72 for the QRPers, & 73 for the QROers out there.

--W5SV, Dave

I run one with my KX3, it is nice.  The only foible to announce is occasional key bounce from an external keyboard.  Need to track that one down.  This is with no common ground between the terminal and the KX3.

It is a little piggish on 9V batteries, the current consumption dictates that you may want spares on hand for a lengthy contest or run with external power.

It's been that way with PC's and Mac's for 15 years.

Your PC is not truly "off" when you hit the power switch. That is the 
ATX specification. To start a PC all that happens is the shorting of two 
pins on the motherboard with the switch. There is power on the 
motherboard until you reach behind and flip the switch on the power 
supply itself.

Before it gets brought up, the battery on all PC's is to keep the CMOS 
clock settings alive, not to boot the PC.

Get ye to the local hardware emporium and buy the $10 power strip with a 
switch. Plug the KPA 500 into said switch. When done using the amp use 
the front panel switch to shut it "off" so it saves settings properly 
then hit the switch on the power strip. Viola! You've saved six watts 
and won't end up on some ridiculous website as a planet hater.

That little tidbit was taken from chapter one of the environmentalist 
playbook.

My house and garage are 100% led lit now. ALL of my "toys" are on 
switched inputs. I live in Iowa. My HVAC system is set to 67 in the 
winter and 77 in the summer. I have a tank less water heater. All my 
toilets are 1.5 gallon flush.

I didn't do this because I'm some kind of environmentalist, I did this 
because I'm CHEAP.

I see the same issue with my KX3.  However, since it goes away after a 
couple of seconds I've got use to it.  Anyone have ideas on the cause?

I know this thread is supposed to be closed now, and hopefully this 
would be obvious, but you should also wait for the fans to stop before 
"pulling the plug". You should always turn the KPA500 off with the 
switch (or the KPA utility) first, wait for the fans to stop, then you 
can use the back switch or a power cord switch.

Ed, Howard,

The HCT draws less than 20 ma with the backlight off, which is typical when
using it outdoors (it has a transflective display).   With the backlight
off, a 9V Alkaline battery should last approx. 20 hours.  2.5 times longer
with a 9V Lithium battery.

With the backlight on, it is going to draw more current naturally, but you
can control that with 5 levels on intensity provided.

And you have the option of powering it externally, if you like.

John,

Because after power off, the fans are powered by the charge in the 
KPA500 capacitors discharging, I do not think that is a requirement - 
but not a bad idea in any case.

Use caution when working with any kind of copper-plated steel wire.  In the
process of bending or forming the wire be careful not to "nick" or
otherwise damage the usually very thin outer cladding of copper.  Don't
drag it over the rough edge of a roof or across the ground.  Any break in
the plating will allow moisture to rust the steel core and cause failure of
the wire.

If the fans are running on the capacitor charge when the amp is turned off,
wouldn't they still run if you pulled the plug?

That is one reason why I prefer hard-drawn copper over copperclad.  But 
then the centers of my antenna are supported rather than trying to 
support the weight of the coax by putting tension on the wire.

Also be careful not to put a kink in the copperclad wire, it will break 
through the copper clad surface and cause the steel wire underneath to 
corrode - it will eventually break at that point.

In other words, I have learned to hate copperclad steel wire.
It was a good inexpensive antenna wire when one could buy a 1/4 mile of 
copperclad electric fence wire at a very good price, but those days are 
no more.

Yes, the stuff is springy and wants to keep its coiled shape unless it 
is held under tension, and will kink easily if it is not held under 
tension.  Hard-drawn copper is much more forgiving IMHO.

John,

The answer is YES, but with any device using any kind of processor, it 
is always better to use the power-off sequence before "pulling the 
plug".  I don't know if this applies directly to the KPA500, but it 
certainly does for the K3(s) and P3 as well as the KX3 and the KX-line.

In other words, to be safe, shut it down before turning off the mains power.

Nope. Just tried it (I had to know).



The fan is controlled by the uC via a BJT and voltage regulator controlled by FETs. Without standby power everything turns off.

If the fans are running on the capacitor charge when the amp is turned off,
wouldn't they still run if you pulled the plug?

John,

Because after power off, the fans are powered by the charge in the
KPA500 capacitors discharging, I do not think that is a requirement -
but not a bad idea in any case.

I suspect they need to be switched into the circuit, done with the logic when the amp is turned Off.

Subject: [Elecraft] K3 for SWL?
Message-ID: <92226EE2-E74F-4D1B-AD69-90FB84C7A7D8@law.du.edu>

I would like to hear from anyone who uses a K3 or K3S extensively for general coverage HF / short-wave listening.

I am looking for a table-top receiver with general coverage strictly for bedroom listening, as the station downstairs already includes a K3/100 system, a KX3 system, two K2s, and a K1.  This seems to be a neglected part of the radio market.  What is available seems pretty slim and, frankly, tinny.  The Sangean ATS-909X has the best reviews but still looks like something I would have taken to the beach rather than sat in front of while transfixed with the global reach of radio.  The new ICOM IC-R8600 looks good, with a range up to 3 gigs, but it?s not available yet and the price is likely to be in the multi-kilobuck range when it is released.

So, being a loyal member of the Elecraft community, I thought about a K3S with just the basic 10 watt TX that this particular radio would never use, no sub-RX, the general coverage bandpass filter and the other accessories that would extend its range down to LF, an AM roofing filter and naught else.

Then I thought about the ongoing commentary about the K3?s audio . . . .   because . . .

I confess that what I am trying to recreate is the warm sound of a 10-tube supperhet in a large walnut cabinet with a cloth speaker grille and an amber back-lighted circular dial driven by dial cord and ganged capacitors while listening to a Radio Moscow announcer crow about Sputnik.  Or so I now fantasize about my early radio experiences in the 1950s.

I will spend some quality time with my own K3 trying this idea out, but thought I would also ask for counsel from the group.  Is there something out there I haven?t seen yet?  Is it reasonable to think about using a K3S in just this way?

Thanks for whatever thoughts anyone can offer . . .

Message-ID: <b1676fc2-a7b4-f76b-9bcc-5ea96bdf0684@sdellington.us>

There was a recent discussion about ATU impedance matching range, and it 
occurred to me that it wouldn't be too hard to make a spread sheet to 
calculate the entire range of an ATU, based on capacitance and 
inductance range and set size.  The data could be plotted on a Smith 
Chart, a separate plot for each band.  It would be a simple matter to 
plug in the data for any of the Elecraft ATU's.  Has anyone done this?  
If not, I'll put it on my list.

This might help. It is a review of the KX3 as an SWL receiver. The K3 would add synchronous AM reception and wider filters.

I was curious, so I tried an A/B test between my KX3 and my Lowe HF-150 Europa. Listening to Radio Havana Cuba on 6100, I eventually preferred the KX3. The Lowe had more highs, especially with the synchronous detector, but the signal was cleaner from the KX3. The KX3 does have a somewhat better antenna, a dipole with a balun and coax feed instead of a wire stapled to the top of the fence. I listened in USB with the filters wide open (0.05 to 4.05), NR off. To be fair, this was a fine signal, S9+10.

This was with my ham-cheap external speaker setup, an $8 audio amp and a $22 per pair set of Pyle 3? speakers.

Well with the short wave stations just about gone, except for the religious stations, I not sure I see the point.  But  my K3s with the sub receiver so you can run diversity receive is the hottest receiver I have owned in my 50 years of doing so.   Way overkill to receive the few multi kilowatt AM stations.

Why don't you just buy a10-tube superhet in a large walnut cabinet with a cloth

about $150.00  The filter caps need to be replaced as there is some 
hum.  Watch Craigs list.  Younger people have no interest in this stuff 
and when their folks or grandparent pass away they just want to get rid 
of them.

Hi Edward,

I had a thought, for a short time, that this would be a perfect use for a K3/0... Until I realised that it doesn't actually even have the option for running a receiver and is literally just a remote head.

Perhaps Elecraft might consider a receiver-only board for the K3/0 which would turn it into a reasonable SWL rig? I'm not sure of the feasibility of this idea, of course, but it's something that came to mind and might be useful for folk who wish to listen only, or run a receiver which can also be used to control a remote K3/100 or similar...

Not sure how much backing there would be though...

73, and a firm left handshake,
John (XLX)

This seems to be a neglected part of the radio market.  What is available seems pretty slim and, frankly, tinny.  The Sangean ATS-909X has the best reviews but still looks like something I would have taken to the beach rather than sat in front of while transfixed with the global reach of radio.  The new ICOM IC-R8600 looks good, with a range up to 3 gigs, but it?s not available yet and the price is likely to be in the multi-kilobuck range when it is released.

So, being a loyal member of the Elecraft community, I thought about a K3S with just the basic 10 watt TX that this particular radio would never use, no sub-RX, the general coverage bandpass filter and the other accessories that would extend its range down to LF, an AM roofing filter and naught else.

Then I thought about the ongoing commentary about the K3?s audio . . . .   because . . .

I confess that what I am trying to recreate is the warm sound of a 10-tube supperhet in a large walnut cabinet with a cloth speaker grille and an amber back-lighted circular dial driven by dial cord and ganged capacitors while listening to a Radio Moscow announcer crow about Sputnik.  Or so I now fantasize about my early radio experiences in the 1950s.

I will spend some quality time with my own K3 trying this idea out, but thought I would also ask for counsel from the group.  Is there something out there I haven?t seen yet?  Is it reasonable to think about using a K3S in just this way?

Thanks for whatever thoughts anyone can offer . . .

If I were looking for something like that I'd be thinking about the Elad
receiver or a second hand Lowe-150, depending on how much you want to spend.

I use my K3 for SWL and broadcast listening from time to time and have 
found the K3 to be perfectly capable of doing the job very well. Just 
use some of the menus and make settings (many to be made) until you are 
happy - and you will find just as good audio as any 10 tube old 
fashioned receiver. AGC and EQ menus come to mind.

I used to think the K3 would be out the door quickly, as I hated the 
stock audio. I am into 75 and 40 meter armchair listening/copy. After a 
while I discovered all the settings and started experimentation. A 
couple of hints and a very good link can be found here: 
http://www.w2blc.net/K3.htm

My K3 has grown roots on my desk. It is all about the settings you make.

Sadly the days of Good shortwave seem to have passed, I also used to enjoy listening to SW in my younger years.

That being said the with the optional General coverage board the K3 does make a good receiver but it lacks the highs in the audio. ?There is a filter board that was added in the audio chain that rolls off the highs above 4kHz, ?depending on your ears that may or may not be a factor for you?

Just getting back on to the ham bands, and not having SWL'd for many years,
what stations are still broadcasting?

I noticed Monitoring Times no longer publishes, and I think I recall
hearing the BBC no longer broadcasts on the SW bands?

Message-ID: <DM5PR02MB25874387A6DFFFFA1D8A98FEB64C0@DM5PR02MB2587.namprd02.prod.outlook.com>

Yesterday I was chasing a 3B8 on 20 cw. Because my antenna (fan dipole) got twisted in the last storm, my swr is over 3:1 and I can't use my amp. The ant tuner in the K3S easily matches it tho. I received an email from a W4 telling me that I had spurious emissions 10 kc either side of my signal. He said in the email, "Jerry, I have been monitoring the activity on 14.041.    I think there is a problem with your transmitter.  When you transmit your signal spreads out over 10 kHz each side of your operating frequency.  I've never seen anything quite like this before on my Panadapter, but when you transmit your signal spreads out over 20 kHz wide with the strongest spike on your operating frequency with spikes going "down hill" on both sides for at least 10 kHz before sinking below the noise level.   Not something that you want to hear, but I thought you would like to know. "
I don't have a separate receiver to check this out but before I go asking a local ham to monitor my signal has anyone ever heard of this before? Suggestions where to start?
Thanks!

Not much, unless your thing is the hell fire and damnation variety of religious broadcasting, whack job conspiracy theorists, or folks pitching gold, apocalypse survival kits, and colloidal silver.  Cuba, China, and sometimes Australia are around and the most prevalent.  VOA still broadcasts, but not to the US (currently) and much of it is not in English.

One of the best resources is http://www.short-wave.info <http://www.short-wave.info/>, which gives live schedules and language information.  Unpublished numbers stations and other interesting stuff can be found if you poke around enough.  The dwindling propagation conditions are not helping.

I use both of my E?craft radios from time to time for SWLing, They work fine.  The sync detector in the K3(s) is excellent.  Usually, though, it?s a GPR-90/GSB-1, Hammarlund PRO-310, or 51J-4 with Lankford?s SSB mods and a Sherwood sync detector for AM.

Hi Jerry,

That is the kind of broadening that can occur if your transmitted signal is
arcing continuously somewhere on the transmission line or antenna when your
key is down.

Fix the antenna and that most likely will go away. "Matching" an arc with a
tuner is illusory, and tends to transfer maximum power into the arcing
site. It can create amazingly broad signals. Back in old analog TV days,
that could have blacked out TV's in your neighborhood.

In any event, don't use that antenna until you have corrected the problem
and your amp no longer faults on it.

Good luck and 73,

Guy K2AV

Instead of SWL Stations, what about Internet Radio?  I  have a bedroom
alarm clock that is Internet only.  there are over 31,000 stations that you
can listen to.
Most of the SWL stations have went to the Internet.  You can listen to all
those stations on your computer but an Internet Radio makes it easier.
I listen to Rock and Roll from England and various Oldies stations around
the USA.
Here is a link to Grace Radio, which I use, but there are others.

Why waste a good Elecraft radio on SWL?

The K3/K3S with the KBPF3A makes Broadcast Band DX-ing interesting too. I've
been doing more of that since the SW broadcasters (other than religious
stations) have largely shut down. 

It is interesting searching for the low-powered local stations around the
country at night. Listened to some Navajo chants from New Mexico one evening
a while back from my Oregon Coast QTH. 

And, of course, there is no end of fervent political talk - almost as much
as the 75 meter Ham band, Hi!

Subject: [Elecraft] lousy cw signal

Yesterday I was chasing a 3B8 on 20 cw. Because my antenna (fan dipole) got
twisted in the last storm, my swr is over 3:1 and I can't use my amp. The
ant tuner in the K3S easily matches it tho. I received an email from a W4
telling me that I had spurious emissions 10 kc either side of my signal. He
said in the email, "Jerry, I have been monitoring the activity on 14.041.
I think there is a problem with your transmitter.  When you transmit your
signal spreads out over 10 kHz each side of your operating frequency.  I've
never seen anything quite like this before on my Panadapter, but when you
transmit your signal spreads out over 20 kHz wide with the strongest spike
on your operating frequency with spikes going "down hill" on both sides for
at least 10 kHz before sinking below the noise level.   Not something that
you want to hear, but I thought you would like to know. "
I don't have a separate receiver to check this out but before I go asking a
local ham to monitor my signal has anyone ever heard of this before?
Suggestions where to start?
Thanks!

My phones are on my ears if I am sitting at my desk.  If I am not
actively pursuing DX or on a net, I am using the General Coverage
module.  I absolutely love having the ability to use my K3s for this
purpose.  And I can make it sound pretty much how I want it to sound.
I find it acceptable even with the onboard speaker, but I prefer my
phones and I will be adding a pair of outboard speakers (SP3).

Is it reasonable?  That is a subjective question.  I think the K3s will
accomplish what you want just fine, superbly in fact.  If you have the
funds to do so, then go for it.  Personally, I would go ahead and use a
loop antenna (80m) and add a mic to make it a full 10W station.

If you already own a K3/K3S, adding the KBPF module makes it a 
spectacularly good general coverage radio. But I wouldn't buy one, or a 
KX3, only for that purpose. Rather, I'd grab one of several very nice 
SDR receive-only radios in the under $200 class. The SDRPlay1 goes for 
about $130; the slightly updated SDR2 about $150. There are several 
others. Feed your computer audio to decent speakers or headphones and 
you're good to go. Depending on which of several free software packages 
you choose to use with it, these radios can be set for pretty wide IF 
bandwidth, so you can get as much audio bandwidth as they're transmitting.

I'm a jazz fan, and listen to jazz stations streaming on the internet. 
About 5 years ago, I bought a dedicated internet "radio" from C Crane. 
It's been a winner. Looks like a small table radio, comes with a remote 
control. I feed it to my living room hi-fi, and also to a Part 15 
"trucker's modulator" set to 87.9 MHz that pumps it around the house and 
to the shack.

There are tens of thousands of streaming sources, most of them run by 
over-the-air broadcasters, but many that are internet only. As others 
have noted, the big shortwave stations we all grew up with have mostly 
gone away.

I just completed a 2 year low-key effort to log an AM BCB station (or
stations - day and night) on every frequency from 530 kHz to 1710 kHz. I
mostly used a Hallicrafters SX-100 and a Hammarlund HQ-145A, both
highly-sensitive and well-calibrated vintage receivers.  To get the hardest
ones, though, the K3 with its synchronous detection was invaluable. For
example, WCBS radio is a powerful clear-channel station on 880 kHz located
here in NYC. Using the K3 and USB, I could copy WLS in Chicago on 890 kHz.
Trying to listen on LSB resulted in a lot of QRM.

I feed my antenna into the "RX-in" jack which bypasses the input filters.  I
sure wish the KX2 had this feature. I use a Bose Soundlink speaker system
plugged into the rear headphone jack. A local oldies station sounds very
nice (although a bit restricted in the treble due to the DSP bandwidth). I
used headphones for the hardest stations.

1620 was the last entry in my log.  Usually, I heard several weak stations
at the same time.  Finally, one night, QSB was in my favor and I heard one
of the stations sign their call letters. Sometimes it took a long time to
identify the stations. I heard stations up and down the east coast and
Canada.  I clearly heard KCJJ in Iowa on 1630 early one evening.

This was actually a lot of fun, especially when the ham bands were closed
down. I was surprised at how crummy (dirty and wide) some of the stations
looked on the P3.

This helped a lot:

https://en.wikipedia.org/wiki/1160_AM

Change the 1160 to whatever frequency you are interested in. I would then
jump to the selected station's website.  If they had a "what's on now" link,
then I could verify that that was indeed the station that I was tuned to.

On a slightly related note, at our last Southern Arizona DX Association club 
meeting we had an unexpected visitor.  He was from the local public radio 
station and had received a letter QSL request from a listener in Norway.  He had 
no idea what a QSL was but after some Googling came up with us and decided to 
see what we could tell him.  He interviewed me and a couple of other guys and I 
sent him some literature.  This may or may not make it onto the air.

What is interesting is that while the station runs 50KW on 1550 KHz, it is 
daytime only.

When I started, I thought that I could avoid making mistakes in 
front of too many people by running QRP. Then I found I could be 
heard around the world. It never fails to surprise that dummy 
loads get out at times, and that what worked yesterday but 
doesn't today. Propagation never fails to be fascinating.

I do have my SWL QSL from KSM on 426 KC. The K3 makes a good low 
band receiver.

Not all 50 KW AM stations in the US are "clear channel" stations. Many 
run 50 KW daytime and 5 KW and possibly directional at night. A few just 
QRT.  With the introduction of the new synthesizer for the K3 which I 
believe is stock in the K3S, one can SWL the highway and traffic safety 
stations.  They occupy locally unused AM channels, often at either end 
of the AM band.  They're scattered out on the Interstates, and are also 
found at airports giving parking directions among other places.  Audio 
quality is variable. [:-)

When I first got the synthesizer [and was still living in CA], I did 
some poking around below the AM band.  Lots of interesting stuff, I was 
really surprised that the DGPS corrections are broadcast there.

I don't know about the we part but at my QTH there is often a nice propagation peak to the west at, and after, my sunrise. At my sunset I see no such thing.

Headphones get endless attention from those of us who live with them on our
heads a lot. 

I just ran across this very interesting site for a company who customizes
the response of their headphones to your particular ears. They have an
interesting demo that you can try with your current phones, as long as you
can access their website using them. 

www.geteven.co

No, that's not a political website. It really is the home page for the

I presume you're talking of the stranded stuff.  Some of that is poorly made. 
Years ago, I had a number of wire antennas fail because the strands rubbed
each other in the wind, scraping off the thin coating coating, then rusting. 
After that, I went with solid or insulated, stranded copperweld.

All:

I picked up an K144XV, a KXV3A and a K3EXREF at a hamfest last weekend from the estate of an SK.

It was boxed as if to say that the hardware is all I need to implement a GPS synchronized transverter in a K3 - minus the GPS Rx. I'm not sure that is the case.   (I have a 10 MHz Zyfer GPS synced reference oscillator) The K3EXREF PLL disciplines the K3's 49.38 MHz timebase. I am reasonably certain that I need  a K144REFLK board to tie the K144XV to the 49 MHz timebase. I assume that the firmware has been written to tie all this to the K3EXREF (It hadn't been shortly after the K3EXREF came out).

Now the needy/horse trading part :)

Anybody want to trade a K144REFLK board for my KXV3A (I already have one in the K3).
I also need a KFL3B-FM 13 kHz crystal filter

Thanks, Russ KD4JO

Subject: [Elecraft] K3S goes Keydown
Message-ID: <000501d27e30$d3198240$794c86c0$@att.net>

I've been operating my new K3S for about 2 months now and love it. 

 

Last week, however, something unexpected happened: as soon as I keyed the
paddles or hit f1 to key the radio (CW), the radio went keydown. Only by
running the power down below 50-70 watts does it finally key up.

 

It has happened a number of times since then. However, it doesn't happen all
the time. 

 

I've disconnected extraneous cables, moved power supplies and computer and
cables. No change. I've reattached cables, relocated equipment back to where
it was. Again, no change. Nothing seems to make a difference. 

 

It is also very sporadic. I can sit down and operate without an unexpected
keydown event. Other times, I can sit down and bang, it's gone key down and
I've got to run the power down to operate. 

 

Until last week, it never happened before. As I said, no changes have been
made to the station: equipment  configuration and positioning, cable
routing, antenna SWR/orientation, etc.  

 

My next step is to find my box of ferrites and start clamping them on
cables-I've never had to do that at this station for any of the five radios
I've ever used here over many years. I figure if any of my past radios were
RFI susceptible it would have been my OMNI VI's. But I never had an
RFI-issue with them. 

 

Any ideas?

Hi Dale,
Sounds like RF is getting in somewhere, somehow!  Have you noticed if it's band specific?  Frequency specific?

This happens to me once in a while, and then mysteriously disappears!

Dale,

Try it on a dummy load instead or your antenna.
If the problem is "cured", then look for a problem in your antenna 
system - RF is getting back into your shack.

If the problem persists on the dummy load, contact K3support.

You have received some good suggestions. I will add look into a common mode choke on you feed line.  You may have one already, if so it may be marginal and a second one may solve your problems.

If you're ever wondering about the tuning range of an ATU, check out the 
blog of K6JCA:

http://k6jca.blogspot.com/

Jeff has done a really thorough analysis of the KAT500, among others, 
and plotted the entire range it is capable of matching on a Smith 
chart.  The plots show not only the maximum SWR it can match, but also 
the specific range of impedances.  The results would apply to any ATU 
using the same component values.  (The range of the  K3 ATU is similar 
to that of the KAT500.)

Many problems with 'RF in the shack' are caused by bad shield
connections in PL259 plugs. It is also very typical for such problems to
appear suddenly or intermittently.

So if the problem persists when the K3S is connected only to a dummy
load, change the coax patch lead as well.

I'm looking into possibly getting involved in MARS. The guy that runs it
locally sent the following question about the KX3:
Can the Elecraft KX3 be opened to permit full operation from 1.8mHz to
29.9999 mHz and do they have installed TCXO (0.5%) frequency stability or
the ability to install the hardware. MARS requires frequency
accuracy/stability to be +/- 20Hz of center frequency on assigned channels
for transmit.
Is this possible with the KX3? If so how?

I used my KX3 on Army MARS without incident. Had no problems with MARS ALE or any of their digital modes (M110A).
But I left due to family health issues.
all you have to do a supplier Mars call sign to Ella craft and they will send you the proper software to unlock frequencies - executable runs on an MS Windows box only, if I remember correctly. Good luck and thanks for your time supporting MARS.

29.9999 mHz and do they have installed TCXO (0.5%) frequency stability or
the ability to install the hardware. MARS requires frequency
accuracy/stability to be +/- 20Hz of center frequency on assigned channels
for transmit.
Is this possible with the KX3? If so how?

From the manual:

   Frequency Stability: +/- 1 ppm typical over 0-50 C. An extended temperature compenstation procedure can be applied for improved stability (refer to our KX3 web page).

So for operation above 20 MHz, you need to do the extended temp compensation. I assume they don?t require a TCXO, but rather equivalent stability and accuracy.

I was a Navy-Marine Corps MARS member, then that branch was absorbed 
into Army MARS.  While with Army MARS, I used my KX3 and KXPA100 out of 
the ham bands everyday of the week for net ops.

The rig can be unlocked for out of band transmitusing software supplied 
by Elecraft.  If I remember correctly, the frequency spectrum about the 
CB frequencies is still locked out (CB plus a guard band on either end).

Doing the temperature compensation procedure will improve your KX3's 
freq stability, but you'll have to test to see if it's in compliance 
with MARS requirements.  There's no guaranteeof this as I understand it.

I think the demographic they are shooting for is likely the folks who see
friends paying $300 for super fancy headphones, and can't spend that kind
of money... maybe those folks look different than you do... I know they
don't look much like me.

I do think they are quite interesting and I believe you are correct in that
they tailor the response to each ear separately. My hearing aids do that
for me. Where I think these phones become less attractive, is that as your
ears change, a new set may become necessary. Also, the way they evaluate
what settings would be "correct" for you, seems too dependent on the
headphones with which you take their test.

I am very happy with the "Gaming" set from Plantronics that I got from BEST
BUY for about $16.00.

Before I call tech support, thought I?d try here.

Just installed in the 2M module in my KX3. I?m on the latest firmware rev.  Gone over the setup instructions several times, and the parameters are all set properly ? enabled, 50 Mhz IF, in the band map, etc.

When I go to the 2M band, the display comes up 122.000.00  ?????

Anyone have an idea?

The demo is just a demo. According to the web site, the phones come equipped
to repeat that process to acoustically match the specific earphones to your
ears and apparently can be repeated as needed.  

It appears to match the audio level at eight different frequencies to each
ear. Like many, my ears are quite different, with large holes in the
response due to too much weapons firing in the Army many years ago. They
compensate for that.

I found the impact listening to their music clips striking.  

I would like to hear if that has an effect on Ham-band SSB comms. 

The headphones are $179 I believe.

FWIW, I do have the beard. Didn't notice any tats or man-buns on the models,
but I wasn't searching for them. I have no involvement with the company. I
just ran across the web site and thought it was interesting to those using
headphones.

I have the K3s feeding JUMA PA1000 with 8...10W.

It is all OK here, we do not have the 15dB rule.

Using IPA is to prevent 100W PA additional distorsion.

Old QST Review gave only 25 dB for IPA 3rd order IMD.

What might be IMD in present-day K3s IPA ?

Any measures available?

Ron -

Thanks for the clarification. I had missed that the headphones are actually
matched once you get them, and that can be re-done as needed. I think that
really makes them attractive.

I am going to share the link with locals, some of whom are not happy with
what they are now using.

I agree, the difference after their "tweaking" was significant.

As I indicated, I am now using a "gaming" headset, because I may make 2 or
3 SSB contacts during the year, and want to be ready... but in my 73 plus
years, I have NEVER been a computer gamer.

Never mind ?

Apparently it was just some garbage in VFO A.  VFO B was on 144.00 where it should have been.  A swap and copy of VFOs fixed the problem.

Subject: [Elecraft] "What would I do with a KX2?" contest winning videos
In-Reply-To: <235a1e5b-7966-cdf5-2f73-126948aebd36@elecraft.com>
Message-ID: <r470Ps-10123i-447A9F1743CB4FBA9F2A158E26E6C419@Williams-MacBook-Pro.local>

I've a story to add to the list. My wife, KI6SLX was lucky 
enough to win a KX2 at the Foothill Amateur Radio Society's 
winter banquet. She was very pleased. Her radio experience is 
all on VHF/UHF FM, so after digging in the manual for a while, 
she asked me, "Do you know how to set it up for repeater use?" I 
dug around for a while, noticed it didn't support FM, and said, 
"I don't think it supports repeaters." A few days later she 
said, "Next time you're at HRO, please pick up a general class 
license manual."

The short answer to, "What would you do with a KX2?" is "Get 
enough incentive to study for a license upgrade."

We could use radios that allow technicians to operate on HF as 
an incentive to upgrade. The Yaesu FT-8900 comes close as it 
operates on 10M, 6M, 2M, and 70cm but it is FM only. It would be 
an ideal radio to introduce Technician licensees to HF 
operation, but it doesn't support SSB. Technicians can't use FM 
on 10M so, catch 22.

(Yes, Technicians can use CW on several HF bands. But, the 
number of new licensees of any class who know CW is tiny. We've 
run out of retired commercial telegraphers who don't already 
have ham licenses.) Nowadays, you get your license, start to 
operate, and then you decide to learn CW.

This is my first time posting to this group. I'm hoping to own my first KX3
in a week or so. I'm picking up a used 2013 KX3.
Is there anything I should look for to update HW wise when I recieve it.
The current owner has said it has the latest FW.
Looking forward to being an active QRPer with this amazing rig!

Hi Bob,

I got  KX3 s/n 2000 as a kit. After reviewing the KX3 mod page I have just
ordered the ball bearing optical encoder to replace the supplied magnetic
with sleeve bearing encoder. I also ordered the heavier duty heat sink.
Both are standard on current KX3s.

Enjoy your KX3, it is now my top end rig and the K3 has found a new home.

Cheers,

Glen, VK1FB

Hi Bob:

Download the kx3 Utility program from the Elecraft web site and check the
firmware version with what you have in the KX3. 

http://www.elecraft.com/KX3/KX3_software.htm

The owner's manual has all the information for checking and downloading new
firmware. If you did not get one with our KX3 it can be downloaded from the
Elecraft web site here:

http://www.elecraft.com/manual/E740163%20KX3%20Owner's%20man%20Rev%20C5.pdf

If you have the 2meter/4meter option installed the manual is here:

http://www.elecraft.com/manual/E740247%20KX3-2M-4M%20Installation%20and%20Op
eration%20Rev%20D.pdf


For any information/updates hardware-wise, they will appear here:

http://www.elecraft.com/K2_Manual_Download_Page.htm#KX3

I know of nothing critical at this time. 

Have fun! It's a great little rig.

Message-ID: <e355ea98-e3c1-1e2e-0b49-03a37da9aced@nycap.rr.com>

I have been using the K3 and KPA500 on AM lately and I have to say, it 
has opened a whole new world to me - or returned me to a past world.

I made a set of AM settings in the EQ and am getting great audio reports 
. The KPA500 develops enough power to keep me in the running 99% of the 
time. No need for a bunch of too heavy to lift big iron equipment.

Life is great!

?I'm not sure how well that will work. I think you need to scheme this one
out.

"Fred is still the simple man, striving to be the king of his castle; Wilma
is still the tolerant* but not-indulging* wife, and Barney (with his wife,
Betty, and infant son, Bamm-Bamm) is still the original wingman, whose
loyalty to Fred often outweighs his common sense."

?I think the key to your solution is the wingman. You could purchase the
KAT500/KPA500 for your Barney and tell your Wilma you are paying him back
for years of loyalty and friendship. If you go this route, let me know. I
can be your Barney. :)

Nah, just keep saying the word 'sale'... that's in most females 
vocabulary even if they don't grok ham radio. ;-)  Then you can mention 
you also saved by buying the kit form, which also keeps you out of her 
hair for hours while building, using and researching for more.  It's 
winnable.  Relate it to her intere$t$, crafting, quilting or whatever.  
Or better yet, get her interested and licensed!

I've read the Elecraft offer in the recent newsletter. Here is my 
understanding of the migration service, which may be completely wrong:

I purchase a new K3S and pay $200.00 to have Elecraft install options 
from my old K3 in the K3S, and I get back a new K3S (containing options 
taken from my K3) plus my old K3 stripped of the options.  Is that 
right, or do I receive only one radio back called a K3S? Where is the 
cost saving or advantage in choosing this service?

I'm puzzled also.... I think you get both radios back, and if you want to 
upgrade the older K3 (like to the new synthesizer board) if you buy the 
board, they'll install it for the 199.99 flat fee.....but I admit, it is 
confusing....

Thanks, Lyle, (and others).

I guess what I really want (and can currently afford) is an upgraded K3, 
not a new K3S.  I have an earlier s/n K3 (#1061), and have done some of 
the mods, but not all of them.  For example, I have the new synthesizer, 
but not the upgraded DSP board, or even the audio output protection 
mods.  I also want to add a second receiver.  So, I guess I will take 
that approach.

Message-ID: <f25dffc3987b4060a966894488a67681@Server.thorntonmostullaw.com>

I did some checking today on my voltage to the K3 using two different routes.

I am using an Astron RS-35m power supply.  It was tuned up to output slightly under 14v.  Normally it mediates through a PG40s backup and switching device, connected to three 140AH backup batteries as well as the power supply.

When I connect the K3 power through the PG40S distribution panel I read 13.3 volts at the K3.  This drops significantly when I transmit, going down to under 12 volts.

I then direct-wired the K3 lead to the Astron using ten gauge wire and a relatively short lead.  Power at the K3 then reads 13.8 and drops only to 13.7 during transmit.

Since I had failures attributed to erratic power supply, my conclusion is the K3 should only be run via a short, large gauge lead direct to a power supply in good order.

I find where the voltage drop is much like checking the drop across a 
resistor in circuit.  ie. use a volt-meter across each end of the 
segment under test. (The volt-meter is parallel to the segment being 
tested)   It may be just a poor connection, or not.

The rule of thumb is to over design the system.? I have nearly the same system with a few differences.? I don't use a distribution panel,? rather my 2x 140 AHr batteries and the solar panel are netted at the 
K3 with a 5 Farad cap 12" from the K3.? I monitor the voltage at the connector of the K3 and only see a .1-.2 volt drop from resting to key down.? So YES make all leads HEAVY and short.

I did some checking today on my voltage to the K3 using two different routes.

I am using an Astron RS-35m power supply.? It was tuned up to output slightly under 14v.? Normally it mediates through a PG40s backup and switching device, connected to three 140AH backup batteries as well as the power supply.

When I connect the K3 power through the PG40S distribution panel I read 13.3 volts at the K3.? This drops significantly when I transmit, going down to under 12 volts.

I then direct-wired the K3 lead to the Astron using ten gauge wire and a relatively short lead.? Power at the K3 then reads 13.8 and drops only to 13.7 during transmit.

Since I had failures attributed to erratic power supply, my conclusion is the K3 should only be run via a short, large gauge lead direct to a power supply in good order.

Message-ID: <CADQmrTFOaMXXoYoqcd3yyJ01-BqQqMRDd0-Mc1rrzomXq0AYjQ@mail.gmail.com>

I recently got my K3 back from the shop. In the interim I had other radios
to use. When I plugged the USB cables from both the KAT500 and K3 neither
were recognized by the computer running Win 7 and drivers would not install
after going through the usual process. The computer is acting like there
were never any FTDI drivers and of course there were as I used the K3, KX3
and a USB8 relay board that uses the same driver. Anyone else experience
this problem or have any suggested solutions?

HiThe first thing I would do is to uninstall any drivers for serial ports you have on your system using the device manager. In the process, you will see a check box to delete the driver. Select this.Reboot.?Next download the ftdi drivers and do the install of the driver software. Then, plug in the USB to serial adapters and let windows do its thing. After this, go into the device manager, ?select the unknown or serial device and install the driver, pointing to the folder containing the driver from ftdi.If this doesn't work, you may have hidden devices. To determine what they are search in Google for uninstall hidden devices. Follow that and repeat.That should do the trick.73 Tom?

Good Evening,

    I have been scanning the lower bands since mid-December.  For the 
last two weeks activity on 160 and 80 meters has slowed.  I was hoping 
for better.  Upon checking SpaceWeather.com I find the sun is still 
streaming ions our way; in fact there is a wind at the moment.

     I am also tracking an incoming storm.  When I first saw the 
forecast I thought there was a typo: 20 inches of snow tomorrow? Eeeek!  
That means I'll need to shovel the roof at least once. Right now it is 
in the 40s and raining cats and dogs.  How and when the temperature 
drops below freezing will make all the difference.  Freezing rain tested 
the antennas again just a few days ago.

    Because of the lack of propagation on 40 meters I have moved it 
forward in time by an hour.  So those of you who have not eaten too much 
tomorrow can find me a bit earlier.  If I am not on the air it is 
because of the storm.  I expect to lose power and maybe my antennas, 
it's just a matter of when.


Please join us tomorrow on:

    14050 kHz at 2300z Sunday (3 PM PST Sunday)
      7045 kHz at 0100z Monday (5 PM PST Sunday)

     73,

Condx on 80 last weekend were excellent from the Midwest for our W9ABD special event.  Low noise, strong signals, and stations in the log from coast to coast, border to border, and several countries.  All at 100 watts.

"I guess what I really want (and can currently afford) is an upgraded K3,

I think you're not alone Chuck.  I recently saw the invoice for my current
K3 S/N 4717 purchased in September 2010.  The K3/100 kit cost $1899.95 and I
added a KXV3A for $109.95.  I had many other options in an older unit (S/N
21XX) and had decided I'd rather roll to a new K3 than do the DSP upgrade
myself.  I uninstalled all the filters, KRX3, KDVR3, KAT3; put them in the
new unit and then sold the older 21XX unit bare bones (KXV3 plus CW filter).

I've since added two KSYN3As and am very happy with the resulting rig.  I
never felt the need for the preamp, USB or 630m capabilities.  I think
Elecraft may have hurt themselves by letting the basic K3S cost escalate
above other options like the IC-7300, Kenwood 590 and Flex 6300 and hence
we're seeing the recent shipping/bundling/upgrade deals.  I wonder if they
should have continued offering the original K3 for those who may not have
wanted all of the features bundled into the K3S base price?  A used K3 is a
very viable option since these are available for around $1500 +/- options,
although I'd definitely want one above ~3626 to get the new DSP.

?I'm not sure how well that will work. I think you need to scheme this one out. 

" Fred is still the simple man, striving to be the king of his castle; Wilma is still the tolerant but not-indulging wife, and Barney (with his wife, Betty, and infant son, Bamm-Bamm) is still the original wingman, whose loyalty to Fred often outweighs his common sense. " 

?I think the key to your solution is the wingman. You could purchase the KAT500/KPA500 for your Barney and tell your Wilma you are paying him back for years of loyalty and friendship. If you go this route, let me know. I can be your Barney. :)

 Check for loose RF connectors. For dome reason, you have a lot of RF in the shack. You probably do not need any ferrite filtering.

Message-ID: <5897552E.50002@yahoo.com>

Hello,

My T1 doesn't tune anymore. I built it only a few weeks ago. It used to
work just fine. Now the tuner no longer goes through the relays clicking
routine and only shows SWR with the LEDs.
Any suggestions? Thanks guys!

Hi Gil,

Make sure you have not accidentally put it in bypass mode. That is the most common mistake made on the T1.

Same thing happened to me recently, rotating the knob didn't work anymore
and it went back to Elecraft to have the encoder replaced.

It was expensive, I should have just ordered the encoder and replaced it
myself before paying for a service call. The tech at work has a desoldering
station that would have made the job easy.

Subject: [Elecraft] K-Pod VFO B
Message-ID: <D1E10466-A72C-43BB-A603-C674FD44FB86@law.du.edu>

Noticed something today that surprised me at first.  When the K3?s VFO B area display is set to the clock and etc. function, and the K-Pod rocker switch is set to VFO B, the K-Pod knob rotates through the display items and does not control the VFO.  As I thought about it, that does make sense ? the VFO B knob itself controls one or the other depending on how the display is set.  I assume, then, that the K-Pod?s encoder output is superimposed on the K3?s encoder B rather than having its own entryway into the VFO.  It?s not a big problem, but it would be nice if the time and etc. display could stay visible yet have the K-Pod control VFO B?s frequency.  When using a P3 with the K3 in split it?s not always necessary to have the VFO B frequency shown in the display area. Is there some way to have one?s clock and B it too?

Well, it looks like the bypass button is no longer working. Neither
tapping or holding the button does anything...

Ted,

On the K-Pod, with the rocker switch in the VFO B position, it will do 
whatever the VFO B knob on the K3 will do.
If you have VFO B Alternate Display up, it will rotate between the 
Alternate Display items, just like the VFO B knob would do.

You could create a macro that would switch the display from the 
alternate VFO B display to the frequency display and use a K-Pod F 
button to activate that macro.

During both nets the power was browning out.  Between the nets the power 
went out twice.  But the second net ran fine at the new time with strong 
signals.  However, just as the last dit dits were being exchanged I lost 
power for a few minutes.  There was a short break in the snow fall 
during the 40 meter net but it is coming down hard again.  On twenty 
meters the snow was causing a lot of noise but I was getting out to at 
least Michigan and Indiana.  On 40 meters my longest reach was Texas.

Now for the next foot to fall :)

Neat idea, Don.  Thanks!  It wouldn?t create a simultaneous display but it would allow the display toggle from the same place where the K-Pod?s VFO B knob is.  The macro would be a cinch ? I think it would just be SWT08; emulating a tap on the DISP button, assigned to an unused tap or hold on the K-Pod.  [that?s a semi-colon after SWT08 ? they don?t always show up that way in the reflector message.]  I?m not in a place where I can test it tonight.  Will try it tomorrow.

On the sideband net at 1800z, we had up and down conditions, 
with our usual backbone stations not being able to hear each 
other. Before the net, I had armchair copy from Eric, WB9JNZ in 
Chicago in my QTH, Los Gatos, CA (SF Bay area). With his amp and 
beam he was coming in S7 over a S3 background noise.

During the net I couldn't hear him at all. At the end of the net 
he was back up to S7 for me, but he could not hear John, N6JW in 
Riverside CA (east of LA).

Conditions were up and down and generally not good.

Has anyone come across any more detail on the KXAT3 (KX3 ATU)? The paragraph about it in the KX3 manual doesn't explain what the match numbers mean while tuning?
When it shows things like "10.2-1" in the VFO2 display does this mean the lowest possible match to the transmitter was 10:1?
No "failed to tune" icon or beep?

It also will not tune if the radio is not sending out an RF.

Have you turned down your RF output to Zero?

Failing that, try resetting.

If that doesn't work, if you don't get any RF out with or without the tuner
in line, then either the finals have failed or you have a RF lead that has
failed internally between the RF board and the tuner.

I would also open it up and have a look to see if everything is firmly
connected.

Is your output power to low?
I built a T1 a few weeks ago and at first it worked good, Then it started acting up...?
I had turned my output power down, turning it back up solved the problem.

Note: As per the manual 2-5 watts is the recommended power setting.

My son has my KX3 and I'm building a K2. Both of us have a set of solar panel that are capable of a lil over an amp at 12v?

We are both looking for a battery idea and a method of hooking it to the solar panels to charge it .

Thank you

You might look into CirKits SCC charge controllers. I use the SCCS3 here 
with two 50W 12V PV panels to keep the 75A-H station battery charged.  
It's an easy-to-build kit.

AGM works well or LiFePo4 (lighter, smaller and more expensive, higher 
operating voltage so better for radio, pickier to charge properly)...  
Neither offgas so they're safe for in the home.  AGM can be used down to 
50% charge, lithium 80% without damage, so you have to compensate when 
comparing capacities (apples/oranges). (The days of lead are ending.)

I'd suggest that you define the battery type you want to use, then get a 
solar controller that is both RF quiet (duh) and can help manage the 
battery chemistry effectively.

LiFePo4 was my choice for portable/RV ops and the charger I use can 
charge from 9-20V (because it charges each cell individually at the 
appropriate voltage/current) so I can charge while driving between 
sites.  It wasn't cheap to get started (battery, management board, 
charger[s]), but size and weight matters on the road (half the size, 1/3 
the weight compared to lead).  The radio prefers it to AGM (it's 
cleaner) from the slightly higher voltage.  The lifespan of lead is 3-5 
years, lithium is 10+ years and can be recharged MANY more times 
(factors when considering cost/year, lithium wins even though they cost 
more initially). Lithium maintains a charge much longer than lead if 
unused.  My next move is to get a small solar charger; which will lead 
into more panels, time and expense (so I'm dawdling).

Learning curve:  Lead charges fade over use, making it simple to know 
when to charge.  Lithium goes full tilt, until it doesn't; so you want 
to monitor each cell and don't get to the cutoff voltage.  The 'knee' on 
lithium is subtle.

WARNING:  Battery chemistry with proper maintenance techniques can be a 
HUGE learning curve and there is a LOT of misinformation out there to 
filter out.  I do not claim to be an expert, but I know some who are.

CAVEATS:

     Some solar controller designs manage via the negative lead, which 
if the battery is also bonded to anything else (an RV), can be a BAD 
thing (momentarily exciting but smelly and potentially expensive).  If 
the battery is not connected to anything while being charged (unlikely) 
it's safe.  [Find a controller for your situation, both designs work but 
management via positive is overall safer.]

     Some LiFePo4 bulk chargers (running through a BMS - Battery 
Management System device) are switcher supplies that generate RF noise 
(shouldn't be an issue with a quiet solar charger).  Ask me how I know?  
At home, I use an Astron linear supply, no noise.  If I use the switcher 
(rare), I'm not operating.

That, in a nutshell, are the high points of a month of online discussion 
with my battery guru.

Wildly expensive is the right word. :)

The Genesun controllers are excellent, and they are almost totally RF 
quiet, far more so than other controllers.  You might hear it very 
weakly on some bands if the cable between your panel and the battery is 
very close to your antenna. Good practice is to use twisted pair for 
that cable and wind 10 turns around a #31 toroid.

Note that Genesun makes a family of controllers, each dedicated to a 
type of battery.  There's one for lead-acid, another for LiFePO4, and 
another for Li-Ion. It's pretty important that you use the one designed 
for your battery type.

I am using 60W foldable solar panel, Genasun MPPT controller 
https://genasun.com/products-store/mppt-solar-charge-controllers/ (they 
are RF quiet) and 5500 AH LiFePo4 battery with built it limiting 
circuitry  which some outlets are selling as a substitute for lead acid 
motorcycle batteries. All works just great with KX3. When using K3 I add 
one more solar panel and 25 AH LiFePo4 battery. This proved to be enough 
to keep going the whole day.

My experience shows that bigger solar panel is safer. My 60W panel in 
real life gives less then 1 A on a cloudy day and about 4 A on a bright 
sunny day when the sun is in its zenith. It also has USB and 12V output 
which can be used for telephone or iPad charging. Unfortunately rainy 
days here are more often then sunny :(

I am sending this to you and to the Post

 

Issue - Speech would drop out randomly during a transmission utilizing the foot switch or the voice keyer and could be heard thru the monitor. 

I checked out the complete station prior to taking it to the Caymans and found no issues making numerous QSO?s. 

Voice randomly dropped out  from the day I got there thru Saturday at the start of the NAQP contest.  Setup was a K3 with the latest download, portable computer, power supply and the station antennas. HRD version 6.3.0.555 logging software was being used. 

During the week I checked all the connections, open up the radio and checked all of the cabling, confirmed that SWR was good (tried 3 antennas)and checked that I was not losing power (tried 2 PS). Right before the contest I changed the foot switch and went to N3FJP Contest software. Not one issue occurred during the contest. The next morning I switched back to HRD software staying with the second foot switch and the problem came back. No cabling was touched overnight. 

At the suggestion of Elecraft, I bench tested the same package at home and the problem was back. I changed to a different computer with a load of HRD 6.2.9.355 and the problem was gone. I swapped back and forth and it went with the 6.3.0.555 software set. I uploaded a fresh/new version 6.3.0.613 and the problem went away. I ran voice loops with memory keyer for 10 minutes 2x without issues. 

Taking it to Hawaii for WPX SSB.

K3 100 watt worked fine at home last week and was transported to the Caribbean.

Started Immediately this morning, some time into a transmission on SSB, keyed with a foot switch or the voice keyer, the transmission just stops. This does not always occur. If I rehit the foot switch, transmission starts up again.  I have not updated the software in 6 months and the 3 different antennas are delivering good SWR. +12 Power does not appear to be going away as the receive function is working and I can immediately continue the transmission.

Manual page 8, in the box titled ?Mode Icons?.  It means that in FM mode a Tone is set, or that CW/Text decode is turned on.

Pete,

That would depend on the software you have running on the computer and 
its use of the computer keyboard F-keys.

If you can send a command from your software to the K3, then the answer 
is YES.  Look in the K3 Programmer's Reference.  You should see the "nn" 
codes for the K3 buttons.  SWTnn is a tap, and SWHnn is a hold.
In other words, to send a command to tap the M1 button, the computer 
needs to send SWT21; to the K3.

73,
Don W3FPR

Yes.  You use the F-key definitions to simulate a tap or hold of M1-M4. 
There is a matrix in the Software manual that gives the codes for the 
various buttons/switches. Loggers differ as to what to put into the 
F-key definitions to indicate a command to be sent to the K3.  N1MM+ is 
CAT1ASC for radio 1 followed by the K3 switch command.  You'll have to 
look them up in your logger's documentation.

One wrinkle to this is that pressing the F-key is a "fire and forget" 
operation ... logger sends the command and gets no notice back when the 
voice message has completed. For normal usage, it isn't a problem, but 
if you are trying to build complex sets of macros, strange things can 
happen.  Note also that the syntax of the logger's command and the 
command to the K3 involve special characters like colons and semicolons, 
and they are essential.

G'day,

CW resonant speaker ? - does it have a filter in it ?

If the frequency is significantly different to the KX2's filter it would explain the extremely low volume.

No,Peter, it "acts" like a filter to focus on CW frequencies between 
approx 500 to 700 Hz while downplaying higher frequency noise. ?Good 
stuff available via Google and Youtube and page 43 of current QST?

Nice speaker but unfortunately won't help me out here. ?I need mono 
output for this speaker and it's only 2 inches and 8 ohms. ?If I could 
get the volume from the headphone jack that I get from the KX2 speaker, 
I'd be quite satisfied. ?Stan WB2LQF

Just use one channel of the amp.

According to the specs, the KX2 external phones jack produces 0.1W stereo (page 65 of the manual). The amp will probably fix your volume problem.

In answer to a list member question ... the speaker is acoustically
resonant and -very- narrow.

I suspect Stan's build and his KX2's filtered output tone are too far apart.

I have two of the original speakers and they are phenomenal!

Ken, "...two of the original speakers..." means you built them or Bill 
built them for you or you mean the "original" Sky-Tec? ?I've tried it 
with the KX2 filter set all the way to 2.8. ?Also tried it with my KX1 
and the same low volume. ?


I don't understand this term "padding" but it was suggested to me in a 
post on the CW list that "most modern transceiver have headset outputs 
that are padded to protect hearing" and I thought that might have 
something to do with this low volume.


I really want to experience this phenomenal sound I've heard so much 
about!!!

Stan,

One of your big problems is that the speaker specified in that project 
is 8 ohms - if you can find a 4 ohm speaker, you will almost quadruple 
the available audio.

The other solution is to use an amplifier.

Stan,

Sorry I wasn't more specific.  My two are the original Skytek units ... one
is still wrapped and in the original box.

Trivia:  They were made in Ukiah, CA.

Several friends have built them ... mostly horizontal versions.  There's
nothing special about the angle beyond esthetics.

I think that speaker is very sharp so the frequency of the audio sidetone must be very exact.

Adjust the sidetone to find exact frequency. It's very sharp and might only work if freq is exact.

Stan,
If you refer to the KX2 Block Diagram (Page 62 of my manual) you will 
see that the PH (headphone) takeoff is a low level and the SPKR(speaker) 
output has an additional amplifier associated with it.  I think Wayne 
did this to minimize the current drain when using headphones, while 
providing usable speaker volume for fixed/station powered use.  Plugging 
a resonant speaker without an amplifier into the headphone jack will 
result in the low volume that you are seeing.

At least that's the way I understand the design.  If you want viable, 
fixed KX2 operation, use a follow-on amplifier with the resonant speaker.

73,
Brian, K0DTJ

Hi,

I picked up a modem splitter (Black Box TL115A) and tried to make this work
with no luck. If I connect my computer's output directly to the KXPA100
serial out cable, it works fine. If I connect the ATU to the KXPA100 serial
out, it works fine. If I put the splitter in place, even if I only just
connect the computer, I cannot communicate with the KXPA100. Same re: the
ATU. Connecting both does not work either. I did get these devices off eBay
(I was shipped two, actually) but neither appears to work - not sure if
this is faulty adapters or if this mechanism just doesn't work in general.
I only spent $10 on them, so it's no big loss, but I'd sure hate to go
spend $80 on the BCE model to have the same results.

Is there a way to make this work without software, so I can still control
the KX3/KXPA100/PX3 via the computer, but the ATU can read frequency data?
I'm considering one of those Y-splitters (one male to two female?) but I'm
worried that this will prevent me from being able to use the computer to
change the frequency on the radio.

I'm still trying to solve this outside of a software solution, that's my
last resort if I can't make something work in hardware.

Thank you all again,
David

Bingo. ?That makes sense. ?I've already sketched out a little 386 amp I 
can build on a popsicle stick and tomorrow I'll dump my junkbox out on 
the kitchen table and go to work. ?I guess I should start looking at the 
manual before I bother people!!


BTW, other than the volume problem I have, this little sucker REALLY 
makes the CW pop. And yes, it IS sharp. ?If I'm not right on, my 
sidetone disappears!

Not quite. A loudspeaker amplifier is essentially a constant voltage 
source. If the two speakers have the same efficiency, the 4 ohm speaker 
will be 3 dB louder. But all speakers do NOT have the same efficiency, 
and Elecraft has been good at choosing small speakers with high 
efficiency for their size.

That speaker in QST is a cute idea and demonstrates the principle of an 
acoustic filter. That's the value of it.

The KX2 and KX3 are carefully designed to maximize battery life for 
portable operation. Part of that careful design is to limit the current 
in the audio output stage. It's really designed for headphones, or with 
external amplified loudspeakers.

BTW -- I think the original question about the output being "padded" is 
a reference to a passive attenuator -- a resistive voltage divider. In 
the audio and broadcast world, components or networks like this are 
called a "pad."

No, the output of these radios are not padded in that sense, but it is 
good practice to add a small resistor in series with the output of any 
audio power amp that connects to a jack, so that it's less likely to be 
damaged when a jack is partially inserted and shorts the output. :)

David, (caution, long explanation)

I am not certain how the "Black Box TL115A" achieves a splitter 
function, but if it does not have smarts to allow only one RS-232 device 
at a time to transmit, it will not work properly.
Similarly, a simple "Y" splitter will not work.

To answer the "why" of the problem - look at the RS-232 switching 
levels.  The driver level for a logic 1 (mark) is at a negative voltage 
while a logic 0 (space) is a positive voltage.  The actual voltage can 
range from +3 to +15 volts for a logic 0 and -15 to -3 volts for a logic 1.

Imagine what happens if one device tries to send a logic 0 while the 
other device tries to send a logic 1.  The voltages will "fight" with 
one another and the result will be garbage.

For a "Black Box" to work properly, it must act as a 'traffic cop' to 
allow only one device to transmit data at a time.  That means the 
'traffic cop' must control the DTR and CTS control lines - and that the 
two devices must honor those control lines to indicate when to send.

The Elecraft KXPA100 only connects the TXD and RXD signals, which means 
it cannot honor the DTR and CTS control signals.  Your ATU may be 
similar.  In other words, there is no 'handshaking' to tell which device 
can transmit data.

For purposes of the KXPA100 (and KX3 and PX3), neither your device nor a 
splitter will function correctly.

The only device that will work on a single RS-232 port with the KXPA100 
(or other gear) is the SteppIR controller or other gear that can be 
configured to only listen to the data between the KXPA100 and the PC (it 
never transmits data).  In that case, a simple "Y" cable will suffice, 
no more complex "traffic cop" device is needed.

You did not say what ATU you are trying to connect, so I can't say how 
it applies to this situation.  If it only listens to the data (either 
has no driver on the DE-9 pin 2 signal [RXD] or disables that driver), 
then it will work with a "Y" splitter cable, but otherwise it will 
conflict with data sent from the KXPA100 to the PC.

73,
Don W3FPR

I tried to check and asked 3 different 599 ops to relay without success.  I was running kx3, kxpa100 and kpa500.

Have a great day!

Yes, saw it too, really good reporting.  There was a very good [in the 
"real engineering facts" department] article some time ago, prior to the 
Samsung debacle.  It was aimed primarily at electric vehicle batteries, 
and touched a bit on large lithium-chemistry batteries for the home.  
Tesla's "Gigafactory" making PowerWalls and vehicle batteries is about 
45 km from us.

It might have been in Scientific American, sadly I don't remember.  But 
I do remember:

The energy density of lithium-chemistry batteries is extraordinarily 
high, and they have an almost infinitesimal internal resistance.  
Consequently, anything that shorts even part of the battery is going to 
result in extreme currents and resulting electrical and pyrotechnic 
displays.

The "secret" to safe lithium-chemistry batteries appears to be really 
good engineering and manufacturing quality control.  I've had one LiPoly 
RC battery I used with my KX1 go up in flames while I was calling CQ in 
the Spartan Sprint.  Fortunately, I was outside on the deck, it was 
externally connected via a pigtail, and I was able to fling it over the 
deck railing onto the gravel driveway.  It's provenance was difficult to 
determine, but I suspect somewhere way way to the west of NV.

If a lithium-chemistry battery ignites, water is not likely to put the 
fire out.  Cheap isn't always a good deal, and I'd never use one 
internal to the radio.

To answer your question, there are 10 ohm resistors in the phones line - one in each channel. So you are losing more than half the audio power in the resistors. (On the plus side, you'll still have an audio output working even if you accidentally short the audio to ground!) 

If you are not using the 2M/4M module for VHF you might be able to install a miniature jack for an external speaker. If you do not use the internal speaker at all, you might just unplug it and connect direct to the speaker connector near the internal speaker. 

Acoustical filters like that work very well. That one looks quite short. I'm used to seeing a smaller diameter and longer pipe. I had one that was driven by a single headphone and produced plenty of volume for a room with my old rx, but that was back in vacuum tube days when receives typically pumped out a watt or more of audio.

Nice speaker but unfortunately won't help me out here.  I need mono output for this speaker and it's only 2 inches and 8 ohms.  If I could get the volume from the headphone jack that I get from the KX2 speaker, I'd be quite satisfied.  Stan WB2LQF

Hi Ron,

Stan was asking about the KX2 which to my knowledge has no 2M/4/M module
available. Wish it did :-).

None the less a spectacular rig.

Cheers,

Enjoying portable QRP phone with my new KX3. Recently began using WSJT-X and Fldigi (for the declining solar cycle) with a Signalink USB/MacBook.

Was using MacLoggerDX for logging phone contacts and now looking for an easy way to log my digital contacts directly from Fldigi and WSJT to MacLogger or other mac based logging program.

If you are successfully doing this I would love to hear from you.

You can get WSJT-X contacts into MLDX automatically by using JTBRIDGE, free software that works very well. Unfortunately, it does not do FLDIGI interface.

Hi Ron,

Stan was asking about the KX2 which to my knowledge has no 2M/4/M module
available. Wish it did :-).

None the less a spectacular rig.

That's the good engineering practice to protect the output stage from 
shorts. In that situation, 8 ohms will get more power than 4 ohms. It's 
the classic "maximum power transfer theorem," where, when the LOAD is 
variable, you get max power when the load Z is equal to the source Z. So 
it comes down to which speaker is more efficient.

I agree with all of that.  The ability to store lots of energy in a very 
small form factor and deliver it quickly as needed (low internal 
resistance) has been and will continue to be an enabler for many of the 
electronic marvels we pursue (including portable electronics, electric 
cars, and off-grid homes).  Unfortunately, that is also precisely the 
physical definition of a bomb, and the key to being able to use such 
capabilities safely is predicated on proper design (quasi-intelligent 
current limiters) and effective quality control (elimination of 
variables at all levels).  It's most likely going to continue to be a 
rocky road, and personally I'm expecting some spectacular failures along 
the way.

Message-ID: <CA+vZ_+J+pe+WbFQhSzrx-ACr=LkMqVizY5mFopc30VNDTuPcMw@mail.gmail.com>

Had my KX2 some days now and very pleased with it.  I thought I would buy
some mini-banana plugs for the counterpoise, but they are too small to
properly fix in the hole provided.  I had assumed that the KX2GNDPLUG would
be a standard size.  Postage from USA makes for a very expensive little
item.

The mini-banana plugs as available from the likes of Amazon are 2mm
diameter.  I can only assume that the KX2GNDPLUG is bigger?

Thanks for any comments,

Hi,
While researching using a serial port for DTR handshaking on the K3 I saw a number of posts about the K3 going into transmit when a computer boots up.  Last night, I found a solution, at least for any USB to Serial device that uses the FTDI chipset (which you should use).
If you open the device manager in Windows and double click on the serial port, you can select Port Settings, and then Advanced.  In this page there are two options.  One is ?Serial Enumerator? which should Not be checked, and the other is ?Disable modem ctrl at startup? which should be checked.
This solves the issue at least for the FTDI chipset.

Further to my previous message, thanks to Ben W4SC,  I have identified the
plug I need.

For UK readers, put Pomona 2945-0 into your favourite auction site and you
will find several at decent prices.

The Pomona 2945-0 uses a set screw to secure the wire.  Pomona 3690-0 
and 4617-0 also fit the KX2 but the wire is soldered to the plug.

Subject: [Elecraft] EFHW
Message-ID: <B3BE05EC-0A68-4667-AF85-D0FF622E04E6@arrl.net>

Wanted to get some thoughts from folks about pros and cons of an end fed half wave for portable/SOTA use, as opposed to just using a random length wire with a counterpoise connected directly to either the KX2 or 3.(I think Eric recommended somewhere around 28? depending on the band coverage).Is there any particular gain advantage? To me the only obvious advantage is not having to deploy a counterpoise-with the end fed usually the length of coax will act for this, and of course the need for a suitable Un-Un,usually 9:1. My preferred antennas these days are lightweight resonant dipoles, which is fine assuming you have room to erect them, and second is a magnetic loop which I?ve had good luck with. I use the Alexloop-very light and easy to set up;ground and height independent generally. But-since you never quite know what will work best I try to be ready for whatever comes up. I have a variety of lightweight poles to use with wires.  I?ve had pretty good luck with throwing a random length in a tree or pole with a counterpoise, usually elevated if possible.The auto tuners in the elecraft rigs are excellent in my book. I think over the years I?ve used a bunch of portable antennas except the EFHW-just curious what the advantages might be.

I suspect you're going to get a lot of opinions on your question 
[end-fed half waves], and a lot more on subjects well removed from your 
questions ... such is the behavior of lists. [:-)

Any half-wave wire fed at the end will present a very high impedance 
[multiple K-ohms] and will require some transformation to a value that 
the Elecraft ATU can handle.  Transformers in the 9:1 [turns ratio] 
range will take 4K down to 50 ohms.  For QRP [i.e. SOTA], they're 
commonly autotransformers wound on small, light ferrite toroids.  The 
high current portion [where most of the radiation occurs] is in the 
center, and a single pole will get it elevated and the antenna can serve 
as two guys for it.  There is little electrical value in elevating 
either end although often, hanging it from a tall tree is physically 
easiest.  A half-wave wire is a resonant dipole and radiates like any 
other resonant dipole ... more or less broadside like a donut with the 
wire through the center.  They are quite popular with the North American 
SOTA folk.

I use a 41.5 meter wire on our wood fence here at home.  It works 
surprisingly well, and is invisible to the HOA.  I run 100 watts, I 
decided more might cause problems with the neighbors and I've sold the 
KPA500 and KAT500.  It is NVIS on lower bands [only 2 meters high], and 
the pattern is somewhat complex on the higher bands but I make a lot of 
Q's with it on CW.  I too use an Alexloop in the field.

Possibly the biggest advantage to an EFHW is that there's usually no 
transmission line involved for field operation and they're thus very 
light and stow compactly.  There is an NA-SOTA Yahoo group you might 
join, lots of discussion about field antennas.

Two distinct advantages of the EFHW: It's high feedpoint impedance means 
a minimal counterpoise is required and very little power is wasted into 
the ground system. Second, the high current part of the wire, which does 
most of the radiating, is a quarter wave from the feedpoint, which can 
usually be much higher than the feedpoint.

The EFHW can be used on harmonics.

The down side is that the high impedance is beyond the range of most 
autotuners, so a transformer or external tuner is required.

I've been using a 40 meter EFHW for portable operations, mostly on 40 
and 20 meters.  I support it with a single 11.5 meter pole about 1/4 the 
way from the far end, like a lopsided inverted V. It seems to work quite 
well.  I have a homebrew QRP tuner, but I use a commercial one for 
higher power.  I've used the same antenna on 15 meters and, with a 
couple longer radials, on 80.  (It's a quarter wave on 80, so there's 
some "RF in the shack", but it hasn't been a problem as long as I keep 
my fingers of the metal parts when I'm transmitting.)

I'll gladly share the design of the QRP tuner.

I have two EFHW antennas. One covering 40 and 20; the other 17. They are 
mounted at about 40 feet and perform equal to regular dipoles.  Feeding 
them is therefore much simpler for portable ops since only one side 
needs to be elevated.  For portable use I feed them with about 20 feet 
of RG/58a, although they can be attached directly to the radio.  I find, 
however, that a bit of coax causes them to be a lot less finicky.  They 
have been my field day and SOTA portable goto antennas for many years.  
Transformers are not difficult to construct and there are some good 
quality assembled products that are excellent.

I had a poor quality Lithium-ion pack explode with the force of dynamite 
while recharging. Shrapnel was embedded in the sheet rock 8 feet away.   
The shock wave was so intense, it ruptured my left eardrum.  I never 
considered that they could be dangerous.  Now I know by finding out the 
hard way.  The PBS show was excellent.

Message-ID: <422EC465-219D-4312-BC52-8F1E20B758B3@arrl.net>

Thanks for the replies so far. Just to clarify-I plan to use the built in auto tuners in my KX2 and 3, so hopefully they can handle the job. I already have a good 9:1 transformer which should work. The primary question is the advantage to the EFHW as opposed to a true random length (not a halfwave at desired freq) with a counterpoise. It sounds like the high current point is a quarter wave from the feedpoint which could be an advantage from the random length. I?ve also seen a variety of ideas on the proper length of coax to use with an EFHW, which as I understand will act as a counterpoise. I now have one of the nice lightweight SOTA poles which would be good with whatever wire I go with. Waiting for some decent weather in the Pacific NW  :))

I would suggest, a good coax choke also.? Cheap easy and good insurance.? The real problem of the 9:1 un un is that IF the transformer is not balanced, there will be CMC to deal with.?

If you are planning to use the autotuner in your KX3 or KX3, I'd strongly recommend the random wire. I work on the basis that there is no "passive" device. Anything between your finals and the 'aether' is either a gain device (external amp) or a loss device (transformer or "balun", transmission line, etc.) The fewer loss devices the better, no matter how efficient you try to make them. 

As others pointed out, to get any real benefit from the EFHW it needs to be a real half wave or very close to it, necessitating a transformer to shift the impedance into range of the ATU or a purpose-built matching network (tuner). Shifting the length from a half wave simply turns the wire into a "random wire".

One other difference between an EFHW and random wire is that it is much easier to spend a lot of money on a commercial EFHW too, Hi

Subject: [Elecraft] EFHW

Wanted to get some thoughts from folks about pros and cons of an end fed half wave for portable/SOTA use, as opposed to just using a random length wire with a counterpoise connected directly to either the KX2 or 3.(I think Eric recommended somewhere around 28? depending on the band coverage).Is there any particular gain advantage? To me the only obvious advantage is not having to deploy a counterpoise-with the end fed usually the length of coax will act for this, and of course the need for a suitable Un-Un,usually 9:1. My preferred antennas these days are lightweight resonant dipoles, which is fine assuming you have room to erect them, and second is a magnetic loop which I?ve had good luck with. I use the Alexloop-very light and easy to set up;ground and height independent generally. But-since you never quite know what will work best I try to be ready for whatever comes up. I have a variety of lightweight poles to use with wires.  I?ve had pretty good luck with throwing a random length in a tree or pole with a counterpoise, usually elevated if possible.The auto tuners in the elecraft rigs are excellent in my book. I think over the years I?ve used a bunch of portable antennas except the EFHW-just curious what the advantages might be.

The low current in the counterpoise or ground system is the main 
advantage of an EFHW over a random wire.  (A random wire "close" to a 
half wave will have a similar radiation pattern, but much higher ground 
system current.)

The feedpoint impedance of the EFHW can be 1500 to 5000 Ohms. With a 9:1 
transformer, that means the SWR will be, at best, somewhere between 3:1 
and 11:1.  Coax is very lossy at such high SWR, so you wouldn't want to 
use more than a few feet of it.  Better, if possible, is to run the wire 
and transformer right to the radio, with just a few inches of coax.  On 
20 meters and above, you may have to slightly adjust the wire length, 
probably shorter,  to compensate for the stray capacitance of 
transformer.  If the ATU won't match it, try shortening the wire a bit.  
That same length will probably work on the lower band, but you may have 
to look for a compromise.

While the coax shield, radio chassis, etc. will serve as a counterpoise, 
a few feet of wire on the ground opposite the antenna may be slightly 
better.  Really cheap insurance, both in money and weight.  Because the 
current is so low, a balun should not be necessary.

As someone else pointed out, another advantage of the EFHW is that you 
don't need a feedline, which saves some weight.  In a way, the near end 
of the antenna IS the feedline, as it doesn't radiate much until the 
current gets higher a fraction of a wavelength away.  Even on the second 
harmonic, where the first high current point is only 1/4 the way to the 
end of the wire, there's another one at the 3/4 point.  Even if the 
first one isn't radiating very effectively, about half the power goes to 
the second, higher one.

It sounds like the high current point is a quarter wave from the feedpoint which could be an advantage from the random length. I?ve also seen a variety of ideas on the proper length of coax to use with an EFHW, which as I understand will act as a counterpoise. I now have one of the nice lightweight SOTA poles which would be good with whatever wire I go with. Waiting for some decent weather in the Pacific NW  :))

Guess I missed that in your post, sorry.  Any conductor of any length 
will radiate, resonant or not ... provided you can get your TX to feed 
power into it.  In all cases, the far end of the conductor is an open 
circuit [High E, low I, High Z] The impedance at the feed end will be a 
complex number.  If the conductor is resonant, the reactance will be 
zero.  If it is not resonant, it will be non-zero and either inductive 
or capacitive, and one more component your ATU has to deal with.  
Elecraft ATU's [even the simplest KX1] can deal with a fairly wide range 
of complex impedances ... with a 9:1 transformer, you should be OK.

Yes, the outside surface of the coax shield will act as a counterpoise.  
Even without coax [direct feed], the radio chassis, headphone cable, 
battery, and you will usually suffice although hanging a few feet of 
wire off your lap from the shield of the BNC may help.

If you do use coax, and you really think you need a common mode choke, 
put it at the rig, not the transformer.  Otherwise you don't have much 
counterpoise. [:-)

Hope this is closer to answering your questions

The classic way to feed a EFHW is to use a tuned tank circuit. The top of it goes to the antenna and the bottom goes to a short counterpoise or the coax shield. You can either tap the coil X turns from the bottom to match 50 ohms or use a link coupling with the appropriate number of turns. 

I use such a system to match a tri-band EFHW on 20, 30, and 40.  Yes, each an electrical half wave using tapped loading coils. The link is 6 turns, tapped every turn. YMMV

In the late 1800's, refineries producing kerosene burned any "gasoline"
byproducts as dangerous waste  - the same stuff we use in pre-Tesla
automobiles today. The reason was that gasoline was "obviously" ar too
dangerous for consumer use. Kerosene, with its much lower volatility and
lower heat per unit was acceptable. 

Anything that can produce very high temperatures very fast can be very
dangerous. Over time, we learn to handle it properly and it becomes
commonplace, like gasoline. 

Obviously there is a learning curve and it's prudent to be careful.

I've used that too, but if one wants to use it on other bands the tapping on
the "tank" to match the impedance and the position or turns on the link can
become tricky. 

An "L" network, when feeding a high impedance load such as an EFHW, is also
a "tank" circuit with the antenna on the "hot" end. But, instead of a link,
the low impedance source from the rig is in series with the tank. 

The end result is the same.

Ahh-the wisdom of Ron AC7AC always wins out!Leave it to an Oregonian... I think he?s right-the less elements you have in the way the better. I?ve used the random length antenna with a counterpoise (preferably elevated) with good results with the KX 3 and 2. I connect it to a dual binding post/bnc adaptor available from various sources including Elecraft. I?ve been hearing a lot about the EFHW but not convinced it?s a major improvement over the random length wire,plus you have to have the transformer,likely still some counterpoise and typically some coax-more chance for losses and more to pack. Actually my favorite antenna for home and portable use is a doublet fed with open wire line, although it?s not as practical in the SOTA world-think light and compact. If I have a choice I like to set this up as an inverted Vee on the edge of a cliff and you gain a great deal of low angle takeoff and gain. I was taught that trick a while back by Russ Carpenter back in the old Adventure Radio days. I used it to good effect in the McKenzie River valley in Oregon.As always I?ll continue to experiment-it?s been fun over the last 40 plus years of portable ops in our great NW. I started back in the ?70?s hauling my Century 21 and Ten Tec Argosy with a 6V lantern battery in the woods up by Timothy Lake by Mt.Hood. Then I discovered this club called Norcal and the great kits they were doing. So-I started building with the NC-40, Sierra,SST, etc. Guess who the designers were-some guys named Eric and Wayne :)) Great rigs to say the least, and then I heard they started this little company ..many rigs and adventures later I?m still taking their gear into the Oregon woods and having a blast, and still experimenting. So-I?m still open to discussion on ideas. Right now I have my old ?gusher? super lightweight dipoles from the New Jersey qrp club;the AlexLoop,W4OL loop, random length wires and even a still useful W6MMA vertical that I keep in my bag of antenna tricks. Wish I could haul my home antenna out-a nice variation of a delta loop fed with open wire line through the old venerable Johnson matchbox. Now I?m just waiting for the pineapple express  (local term for a warm deluge of rain) to end so I can start getting out in the woods and mountains.Us Oregonians are a bit different :))

I suggest you consider finding a good, used Drake R8 receiver on eBay.  The
sound of AM HF broadcasts (yes, they are still there -- e.g., Radio Romania)
is second to none.  And listening to SSB has it all over my K3 and other ham
transceivers from a fidelity viewpoint.

Hello all

I hope this is not a dumb question .......... I have a K3 (not S) which has
the sub receiver and has been updated with the KIO3B.

I have main RX audio available on the USB port.

Can I have the sub RX audio on the USB port - and if so, how is it done ?

Many thanks

Sub receiver audio is available on the *RIGHT CHANNEL* of USB Audio

and RING of the headphones jack.

Was working fine, but today I have no output from the K3S on WSJT MSK144.  If
I select "Tune" on the WSJT screen and try to adjust the Mic gain control, I
can't get any reading on the ALC meter.  Any suggestions would be
appreciated.

No need to spend much money on an end-fed half-wave antenna. The EARCHI
 matchbox design is cheap if you do it yourself, and reasonable if you buy
the kit or pre-built from them. If you want it to be a true half-wave,
choose the wire length accordingly.

The reason your antenna was a lot less finicky with a bit of coax is that the
EFHW antenna requires a return path for the RF field. Theoretically, without
a return path, the antenna won't radiate at all. The recommended setup for
this antenna is for a .05 wavelength counterpoised to be used. EZNEC models
indicate that there is little benefit to going much longer than .05
wavelengths, and a quarter wavelength is actually less effective than the
shorter lengths.  If no counterpoise is used, then coax shield becomes the
counterpoise by default.

Check the "Master" level for "Speakers (USB Audio CODEC)" in Windows'
Volume Control.  If things got changed, perhaps your Windows Sound
Settings also got changed.

Message-ID: <CA+ZptLm7yM9PYsGsVmqZO=egGZC3KK7oUGP60vSFZkK5UkEeaA@mail.gmail.com>

Just noticed that using the internal tuner, the TUN PWR option on the KX3
seems to be ignored, at least for any value less than 3W.  That is to say,
if I choose any transmit power less than 3W, the KX3 still uses 3W.

Am I doing something wrong, or is there some other option overriding this
one?  I'd much prefer to use the lowest amount of power practical when
tuning.

John,

Is there any chance you plugged something into the K3S LINE IN jack? 
Doing so turns off the CODEC audio out and the audio is taken from the 
LINE IN jack only.

If nothing in the LINE IN jack, check the levels for the CODEC in your 
computer.

The ATU needs about 3 watts to find a good match, and that is the default.

If that's the case, it might be nice in a future firmware to make 3W the
lowest value for tun-pwr.  As it is today, it makes it appear as though you
could select values as low as 100mW, even though you actually can't.

TUN PWR sets the level for the TUNE button, not for the ATU TUNE button.

Nick,

You should be able to adjust the (transmit) power level well below 3 
watts right now, but if you do an ATU TUNE, the power used for that 
should be 3 watts.

ATU TUNE and TUNE are two different things - check the manual info for 
TUN PWR in the listing of menu items.  It clearly states that the ATU 
TUNE uses either 2 or 3 watts.
TUNE should follow the power setting if TUN PWR is set to NOR.

73,
Don W3FPR

I am not sure I understand your problem, and therefore my potential solution may be irrelevant.

I experienced sudden extremely low power output recently during a contest.

The solution was to re-install the firmware and recalibrate TX power.

I later determined the cause was voltage drop coming from the power supply.  I fixed loose connections in my power supply and put a short lead from the supply direct to the K3 and things are going well again.

Problem fixed at zero cost.

Don,

No, nothing in the LINE IN jack.

The audio setting on WSJT did also get changed.  I put it back on CODEC.

It is working now.  I had to set CONFIG > MIC SEL = LINE IN, and increase the power slider on the WSJT screen.

Thanks,

John

Question is what do you want to do with the sub RX audio?

I.e., for RTTY you'd need to run a separate instance if MMTTY and set input from RTTY channel.

Maybe not so wrong.  The sub audio is on the right channel of the USB audio but you may have to go into the Windows Sound set up and the USB audio Codec to be a 2, channel, 48000 Hz device.  Windows sometimes sets this to be a single channel device.

Bill, Joe and Fred

Thanks for your quick replies. It certainly WAS the correct question to ask.

Fred has put his finger on the problem; my Windows settings had defaulted to
single channel audio. My question turns into "how do I get Spectran to look
at the other channel" but that's not an Elecraft question.

Why am I interested in the audio from the second receiver ? This goes back
to a problem with my K3 which on 28MHz has a large number of receiver
birdies - I posted about this a couple of weeks ago. The situation has been
improved by tightening all the panel screws absolutely as hard as I can. I'm
no weakling but it seems that I was being a bit too cautious. But some
birdies remain, and I noticed that they are at different levels and
different frequencies on the sub. So I was making a careful check and
listing the frequencies and signal level, using Spectran. But so far, only
on the main rx. Hence my question.

I have fitted the KFL3C-200 Filter to my K3. There was no paperwork with the
filter, to give a frequency offset, if any. 

 

With the offset set to zero, nothing seems to pass through the filter.  I
have experimented, and an offset of -1 seems to do the job.

 

Have I missed something? Suggestions welcome.

I work portable with about 1 ft of coax to my end-fed. Never really had a
problem making contacts. Guess I could do a lot better with a longer coax
or with a counterpoise?

If they are end-fed half wave multiples without matching at the 
feedpoints, there has to be a lot of loss in the coax.  Even if there 
are 9:1 transformers at the feedpoints, there still could be quite a bit 
of loss, as the SWR is very likely over 3:1.

Do yourself a favor sometime and measure the 2:1 SWR bandwidth and use the tutorial to calculate how much loss you really have.? Just for grins.....? It gives you a bench mark.....

It wouldn't hurt to add a counterpoise of 6-8 feet, just a single wire 
on the ground opposite the antenna, but it may not make much 
difference.  (I'm assuming EFHW, not random or quarter wave wire.) That 
short coax, the radio, the headphone cable, etc. is probably serving as 
an adequate counterpoise.  You definitely do NOT want a longer coax, 
unless there's a matching network at the feedpoint to keep the SWR low.  
Even then, the long coax would only be advantageous if it allows you to 
place the antenna in a more favorable location.

Message-ID: <22f108c3.3fa0e.15a25135f82.Webtop.59@optonline.net>

Just a couple of months ago, on December 7, I purchased a KX1. ?It was a 
replacement to the KX1 I had built several years ago: my entry into the 
Elecraft world. ?I thought I had "outgrown" it so I sold it.

Fast forward through my K1, K2, K3, KX3, and now KX2/KXPA100 setup (plus 
other stuff like the K2 amp, the KAT100, the PX3, an earlier KXPA100 for 
the KX3....lots of other stuff plus the mini-modules) and we come to 
today. ?Elecraft has made a small fortune on me!?


We're having a blizzard in New York. ?My picnic table out back has over 
12 inches of snow on it. ?As a prisoner of the house, I decided to do a 
little operating; ?However, 40 meters was dead and so was 30 meters. ?It 
wasn't so hot on 20 meters either. ?I went down to the living room and 
built a fire. ?But gosh, I really wanted to operate...


So I brought my KX1 down to the living room. ?I stretched a 40 foot 
length of {high loss} RG174 from my shack to the fireplace. ?I have a 67 
foot bent up doublet in my attic managed by an SGC231 autocoupler and 
that's where one end of the RG174 extension coax went. ?The other end 
connected the antenna to my KX1 on AA batteries. ?With less than 13.9 
VDC, the KX1 doesn't have the oomph required to kick the autocoupler 
into tune mode. ?No problem. ?I just used my QRO setup to find the match 
on 14.030. That would give me a few kHZ either side with a good SWR.


So there I am, sitting in front of the fireplace with a rig on batteries 
putting out maybe a watt +/-, a high loss connection to the antenna, a 
coupler with some degree of loss, a freakin' blizzard outside, a bent up 
antenna in my attic and a foot of snow on the roof and conditions on 20 
meters reportedly "Fair."


Well, guess what. ?I worked a whole pile of stations - Minnesota, New 
Mexico, Florida, Hungary, Ireland, Germany and the Bahamas. ?After an 
hour, I brought the rig back to the shack and promptly worked ?V53DX, a 
new QRP country for me.


Thus, it was with more than a little sadness that I logged onto the 
Elecraft website and saw that the KX1 has been discontinued! ?I don't 
recall seeing any email announcements about this or any chatter on this 
reflector about it either.


I certainly understand that business decisions must be made and change 
is inevitable. ?In fact, I'm surprised that the K1 didn't go before the 
KX1.


I just thought I'd take the time to salute one of the greatest QRP rigs 
I've ever had the pleasure to build and operate - twice - and WOW - I'm 
happy that I gave this new KX1 to myself for Chistmas!


During the period of time between my first KX1 and this new one, I 
explored lots of other QRP rigs because I was curious. ?I spent a lot of 
money too! ?They were all well engineered. ?They all worked. They all 
had their own uniqueness. ?BUT the KX1 distinguished itself because it 
had everything one needs to operate right there onboard. ?The LNR 
Mountain Toppers, for example, were about the size of a pack of 
cigarettes. However, the operator had to have an outboard key, an 
outboard power supply and an outboard antenna tuner. ?That's more like a 
full carton smokes. Same for the LD-5 and LD-11.


The thing about the KX1 was its apparent simplicity which masked its 
elegant design and robust menu. ?I love my KX2 with its dual watch 
function, autospot feature and filtering. ?But now it's hooked up to the 
amplifier and it's no longer a candidate for "grab and go" operations. 
?The KX1 was (and IS for me) just plain FUN and all in one nice package.


Sorry to see it go west.

Stuart,

Look on the filter itself.  The offset should be marked on the paper tag 
affixed to the filter.
I don't know about the new 6 pole filter, but that is true for the 5 
pole filters, and I assume it is the same for that one.

In other words, the offset is not on separate paperwork.

Stan,

Thanks for the inspiring tale! 

I did an outing with the KX2 yesterday and had excellent results. I was using a 4-foot 20-meter whip with 13-foot ground wire, sitting on a bluff in the Antelope Valley, gazing at the San Gabriel mountains. Worked stations all over the country, including a W1 on RTTY (with the keyer paddle).

I, too, will miss the KX1. It was the first radio I used SMDs in. But the KX2 is about the same size and has so much more capability.

Being able to easily run both main and sub in RTTY is why I 
still use cocoaModem on my Macintosh. (It suffered from serious 
incompatibility with a new version of the OS a few versions ago. 
I still have a backlevel machine with full functionality.)

It has a dual RTTY mode with two decode windows, one for the 
main receiver and one for the sub, like using stereo headphones 
for CW of SSB. It is the only program I know of, for any 
platform, that does this.

Yes, sad but probably inevitable.  I just sold my KX1, I built it in 
late 2004.  Lots of contacts from lots of places.  I'm now 13 years 
older, adventures in my 20's are "reminding" me of them orthopedically, 
and field operations for me are rapidly becoming something in the past.  
I still have my K2, and do use it, but generally within sight of the truck.

I suspect the primary reason for discontinuing it is parts availability, 
the design is creeping up on 20 years old.  Then of course, there's the 
KX2 coupled with every ham's desire to have the latest and greatest.  
KX1 is still a great trail radio.

Definitely a sad time, when things change. I, too, had some great times with my KX1, which has gone to be with a friend in San Antonio, and I hope he gets as much enjoyment from it as I did. 'm sure he has, and is. Mine went to Ukraine with me when we went to adopt our daughter in 2004 (my excuse for buying it). It was a real life saver, or at least a sanity saver. Dropping a window out our 7th floor apartment and stringing another wire across the floor (far from ideal, kind of upside down!) still netted me contacts. True, not lots of contacts, but contacts nonetheless, and it truly helped me with the one thing about the adoption we didn't anticipate: being locked in the apartment (yes, quite literally, with a key and everything) between orphanage visits because the adoption people just didn't know what to do with a couple of blind/disabled people. And, yeah, no trips to the Internet cafe for me either. Nothing between me and the ether except a TeNe-Key. Yep, good times. While I love my KX3, and my K2 (which has its own really neat story), I think it's pretty hard to replace the memories with that KX1. So, vy 73 to a legend, if only a legend to me. And, probably, you. :)

Thanks, Ken.  A number of other replies also suggested a Drake, though most mentioned the R4 series.

At this point I am thinking of something still in production, since I have never gotten into doing restorations and buying used from afar can be an expedition to the unknown.  I plan to look at what?s available at hamfests . . . where I can touch the goods.

Following the advice I received from others I am trying out two possibilities.  One is the KX3.  I tried that last weekend.  It has what seems like very good sensitivity, and operational ease, though to use it for arm-chair type casual listening will require an external audio amp and a decent speaker.  The other possibility ? at less than $200, near the low cost end of the scale ? is a Sangean ATS 909X.  TI bought one and it just arrived.  I?ve not yet had a chance to hook it to a real antenna.  I plan to do a side-by-side with the KX3 and will happily share my impressions off list with anyone who asks.

My thanks to the many people who replied to my inquiry post, both on-list and off.

    I suggest you consider finding a good, used Drake R8 receiver on eBay.  The
    sound of AM HF broadcasts (yes, they are still there -- e.g., Radio Romania)
    is second to none.  And listening to SSB has it all over my K3 and other ham
    transceivers from a fidelity viewpoint.

Skip,

My discussions with those 'in the know' at Elecraft in early December 
revealed that the problem for the KX1 is the enclosure, and not the 
parts inside.

So if you have a KX1, it should be able to be maintained and supported 
for some time to come, but if your enclosure "wears out", there are no 
replacements - therefore, no new kits.

73,
Don W3FPR

George, KJ6VU, is a principle in the Pack-Tenna venture and a good 
friend.  I don't have one but I've seen it.  It's a fairly slick package 
for field work and it does not need an ATU which might put another 0.1 
watt into the radiation resistance instead of heat in the ATU.

?Thanks Scott. I use the Par EndFedZ EF-10/20/40 and EF-20/40 depending on
what's in the bag at the moment. These are resonant and I'm assuming the
KX3 tuner is enough to keep the SWR low. The radio always seems happy.

I will add up to 8 feet of wire next time out and try some A/B tests.

During this thread there's been a couple of comments that kind of challenge
my way of thinking. I would never have thought a random wire would be
considered superior to a resonant antenna. I also don't equated high SWR
with high loss. My home antenna is comprised of a dipole fed with 600 ohm
ladder line through a 4:1 BALUN. It's about the best antenna setup I've
ever had and I use it on all bands 80 (where it is resonant) through 6. The
KX3 and the Flex tunes it nicely and the log fills up.

Threads like this get me questioning everything I thought I knew. That's
not a bad thing.

Hi Stan and All,

No snow here, 106 fahrenheit here. Just been down to the PO to pick up my
new heat sink and optical encoder for the KX3, beside me on the desk is the
KX3 line, KX2 (Sweetest rig ever) and KX1 which I love.

Thanks for your nice email and thanks Elecraft for the KX1 (RIP).

Cheers,

Glen, VK1FB

SDRplay comes immediately to mind - see at sdrplay.com - because it 
covers from DC to light. I am going to get one, run it from a laptop, 
and use it for SWL, scanning, and local BDCST. All modern and very small.

MixW has a dual channel decode mode.  N1MM Logger+, and WiteLog will
both open two RTTY decode windows (using two copies of MMTTY), DXLab
Suite will open three RTTY decode Windows (using MMTTY, 2Tone and the
K3 Decoder or a hardware TU) which can be assigned to either receiver,
and Logger32 can open two decode windows (one for each receiver).

Dual channel decode is quite common in the Windows world.

Message-ID: <CAFA9ujt1CP22Q6CNZOkVV=_JV8=mfjS1vXv89WKw9z7gxL1Jqw@mail.gmail.com>

Hi... with all the hoopla over the new $7K Flex amplifier I was feeling a
little power envy so went on a search for options. I own an Elecraft KX3
and absolutely love the rig quality so I'm thinking about the KPA500/KAT500
combination assuming I'll get the same quality equipment.

Is anyone running this combination with the Flex 6500 who might share their
thoughts, configurations, hints & kinks?

I'm thinking the combination makes sense for me because (my decision
points):

1) Being a low power operator, 500 watts seems a lot more manageable than a
nuclear powered 1.5 KW setup. It seems like a good, safe step.

2) No electrician required. I think I can run it off 110 VAC already in my
shack.

3) If I understand correctly, there is little or no integration effort
required. I'm looking at putting it inline with the RF path and adding a
PTT connection. Voila.

4) The KX3 is able to easily tune my 600 ohm ladder line fed (via 4:1
BALUN) 80 meter dipole on any band so I would guess the KAT500 wouldn't
have an issue.

Is there a reason I shouldn't consider this setup with the Flex? The only
other thing that caught my eye was the ACOM 1010 which would also require
an external tuner.

Kevin,

I don't think you can go wrong with the KPA500/KAT500 combo.  I use one 
with my 6700.

Download and install DDUTIL on your computer which does a great job 
integrating the 6XXX and amp combo together.  A couple of things DDUTIL 
will do for you:

     - Drive power by band
     - Amp will follow the 6XXX band changes
     - Tuner will follow band changes as well as band segment changes

It's very slick.  500 watts gets the job done.  The only time you may 
wish you had more power is on 160 and 80 for dxing.

I have toyed with the idea of moving up to an amp.  My problem is I live in an urban location with houses close together.  I am concerned that with too much power I might start lighting up the neighbors' TV's and computers.

I think the best money invested is in the antenna.  I got a used 3 element SteppIr a few years ago, paying about what it would have cost for a KPA 500 by the time I added a rooftop tower and used rotor.  I have been very pleased with what I have been able to do using 100 watts and that antenna, and I have found only a few situations where power would have helped me.

Of course, now we are down in the solar cycle and I am now looking at what I can do to improve low band performance.  I am contemplating a 43 ft vertical and a SteppIr DB 18e.

I have owned pretty much only Elecraft over the past decade and a half and I have been well pleased with the quality of their equipment.

Beautiful obit for the KX1 Stan. Ops like you will remember it like us O.T.s remember our 6L6 crystal controlled oscillators built on a breadboard. Newer rigs do as well (sometimes better) but are never the same. 

Waaay back in the 1950's I volunteered to operate NCS for a RACES exercise in Southern California at W6CV, owned by a good mentor, Brook Sawyer. The station had a room of its own in his homw with a state-of-the-then-art Viking II A.M. transmitter and big HRO receiver hooked to a dipole on his hill top via open wire line. I spend a long day managing that net, constantly impressed with the station. But then that evening, as I drove home in my 1947 Studebaker Champion, I remember looking forward to firing up my one tube 6V6 oscillator to look for a contact with my Hallcrafter's S-38 receiver. Running the big rig at W6CV was one thing. Pounding brass with my 6V6 oscillator was a whole different experience. 

Certain rigs we never ever forget, no matter how much "better" what followed has become.

Just a couple of months ago, on December 7, I purchased a KX1.  It was a replacement to the KX1 I had built several years ago: my entry into the Elecraft world.  I thought I had "outgrown" it so I sold it.

Fast forward through my K1, K2, K3, KX3, and now KX2/KXPA100 setup (plus other stuff like the K2 amp, the KAT100, the PX3, an earlier KXPA100 for the KX3....lots of other stuff plus the mini-modules) and we come to today.  Elecraft has made a small fortune on me! 


We're having a blizzard in New York.  My picnic table out back has over
12 inches of snow on it.  As a prisoner of the house, I decided to do a little operating;  However, 40 meters was dead and so was 30 meters.  It wasn't so hot on 20 meters either.  I went down to the living room and built a fire.  But gosh, I really wanted to operate...


So I brought my KX1 down to the living room.  I stretched a 40 foot length of {high loss} RG174 from my shack to the fireplace.  I have a 67 foot bent up doublet in my attic managed by an SGC231 autocoupler and that's where one end of the RG174 extension coax went.  The other end connected the antenna to my KX1 on AA batteries.  With less than 13.9 VDC, the KX1 doesn't have the oomph required to kick the autocoupler into tune mode.  No problem.  I just used my QRO setup to find the match on 14.030. That would give me a few kHZ either side with a good SWR.


So there I am, sitting in front of the fireplace with a rig on batteries putting out maybe a watt +/-, a high loss connection to the antenna, a coupler with some degree of loss, a freakin' blizzard outside, a bent up antenna in my attic and a foot of snow on the roof and conditions on 20 meters reportedly "Fair."


Well, guess what.  I worked a whole pile of stations - Minnesota, New Mexico, Florida, Hungary, Ireland, Germany and the Bahamas.  After an hour, I brought the rig back to the shack and promptly worked  V53DX, a new QRP country for me.


Thus, it was with more than a little sadness that I logged onto the Elecraft website and saw that the KX1 has been discontinued!  I don't recall seeing any email announcements about this or any chatter on this reflector about it either.


I certainly understand that business decisions must be made and change is inevitable.  In fact, I'm surprised that the K1 didn't go before the KX1.


I just thought I'd take the time to salute one of the greatest QRP rigs I've ever had the pleasure to build and operate - twice - and WOW - I'm happy that I gave this new KX1 to myself for Chistmas!


During the period of time between my first KX1 and this new one, I explored lots of other QRP rigs because I was curious.  I spent a lot of money too!  They were all well engineered.  They all worked. They all had their own uniqueness.  BUT the KX1 distinguished itself because it had everything one needs to operate right there onboard.  The LNR Mountain Toppers, for example, were about the size of a pack of cigarettes. However, the operator had to have an outboard key, an outboard power supply and an outboard antenna tuner.  That's more like a full carton smokes. Same for the LD-5 and LD-11.


The thing about the KX1 was its apparent simplicity which masked its elegant design and robust menu.  I love my KX2 with its dual watch function, autospot feature and filtering.  But now it's hooked up to the amplifier and it's no longer a candidate for "grab and go" operations. 
 The KX1 was (and IS for me) just plain FUN and all in one nice package.


Sorry to see it go west.

Kevin,

You will find success with the KPA500/KAT500 combo with any transceiver 
that uses an RCA jack for KEYOUT.  Elecraft announced last week that it 
is working on adapter cables for transceivers which use connectors other 
than an RCA jack for KEYOUT.

You will be pleased with the KPA500/KAT500 with almost any driver 
transceiver.

Great story.  Thanks for sharing it, Stan.  But I want to be sure I am reading it right.  The coax went into the fireplace, which had a fire burning in it at the time,  up the flue, and out in the attic where the doublet is?  I suppose that?s what?s called an end-fire array.  

I?d like to buy some of that coax.  Could you say what type it is, or was?

Ted, KN1CBR

Whoa there, Ron! ?Next week is my 68th birthday. ?I ain't no kid! ?My 
FIRST rig was a crystal controlled 50L6 fed doubled DC by a 50Y6 using 
one half of the line cord and a cold water ground. ?It was called "The

THAT is THE rig that earned me a QSL card from WA1BVN (clearly a SK by 
now) up near Boston who wrote on it, "Solid 579, Stan, you must have had 
your foot in a water bucket."


Oh, lest I forget - the antenna was my bedspring. ?Remember when bed 
springs were real metal springs? ?I lived in an apartment and couldn't 
have an antenna. ?I'd heard about "loading a bed spring and, as a kid, I 
totally fell for it. Thank God for Pi Networks. ?I ran that bed spring 
for several weeks until I discovered magnet wire.


Now THAT"S A MEMORY, Ron, right up there with my little KX1 and your 6L6

Are you plugging into a USB hub?  There are some device which really need a powered USB port,  and not necessarily just a port on a hub that is powered.  Try plugging directly into a port on the Mac Mini.  You can always move the mouse or keyboard to a USB hub.

One of my fondest KX1 operating memories was working F5VHY on 20m CW while operating pedestrian mobile with my KX1. 
I was using a 4 foot loaded telescopic whip and a 13 foot drag wire and standing out in the middle of a field at Lobstercon.

Specifically the error means that something plugged into the USB ports of
the computer is exceeding the amount of power it should be drawing. There
could be several reasons, including a short in the USB cable or a device
that doesn't follow the protocol for getting more power from the port.

Unplug everything and work your way back until you find the culprit.

Good luck,

I wanted to thank everyone who commented on this thread. I felt an obligation to wrap it up since I ?poked the hornet?s nest? :)) I did get some good information and some interesting comments. It?s always fascinating to see how things morph from the original post.One thing I did realize is that there still is some confusion over what is an end fed halfwave; a fair amount of folks conflate an end fed wire of any length with a resonant half wave. While it?s true that a resonant half wave may be a non resonant random wire at bands other than it was made, that?s not exactly a useful premise for my needs. So-in the interest of closure I?ll post the original question in the clearest fashion I can and ask that any thoughts on this please email me directly and if i get some good responses I?ll post to the list so we can all have that to enjoy.
I also want to keep it Elecraft related as best I can. ,Ok-here?s what I?m asking: Think about a SOTA (summits on the air) outing where I?m hiking to activate a summit
and the goal is to travel light. ?Ounces are pounds? as the saying goes.Radios are either a KX 3 or KX 2 both with autotuners. I have a number of options I use already including resonant dipoles; verticals and loops, and I plan to continue to use these as conditions require. You never know what?s the best option until you?re actually at the site..One other option is either an end fed random wire with a counterpoise (length selected to avoid a resonant quarter or half wave-there?s charts out there to help select good lengths) or an end fed (resonant) halfwave cut to resonate at the desired band. Think say, 66 feet for 40M give or take. Now-when I use a non resonant random length wire I feed it directly off the radio (BNC-binding post adaptor). With a resonant halfwave I would (and have) used a 9:1 transformer, coax (variable length) and perhaps a common mode choke, and perhaps a short counterpoise. Between just those  two antennas is there any advantage to using the resonant halfwave over the random length wire? Is there more gain? Better takeoff angle? More lobes ? Would this justify packing the extra stuff for the resonant halfwave? I?m guessing a lot will depend on terrain/height,etc so may be hard to answer, but that?s the question, and that only. I imagine efficiency may be a factor, but if I can eliminate a transformer,feed line,and choke and feed directly to the radio that should help eliminate some losses.
So-it isn?t about how to build/buy an EFHW; what to use at a home station,etc. It?s just this one question. Like i said-I have a few good answers but curious if there?s something I?m missing about the EFHW over the random length antenna. Thanks everyone, and I hope we all can get out and enjoy our great rigs as much as possible. The KX 2 is the radio I?ve been dreaming about for a long.long time and now I have one...

Hi all,

I finally got to translate an article I wrote about using FLDIGI (or any other Windows program) on a cheap LINX 7" tablet running Windows 8, and interfacing it to a KX3. The info may be useful for other tablets/phones with a 4-pin TRRS connector, and any Android or iOS software.
(beware that Apple reverses the MIC and SHIELD connections, Google is your friend ...)

Since this tablet has a camera in the front and back, it could even be used for some live SSTV reporting  ;-)

You can read the article here :
https://on7dq.blogspot.be/2017/02/my-kx3-digimode-interface.html

Hope you enjoy it, and may it inspire some others to get on PSK or other digimode.

It is indeed a sad but inevitable occurrence, time and technology move forward !
The KX1 was my first venture into the world of Elecraft, I bought mine in 2010 and still use it, it has gone everywhere with me in my travels, from mountain tops to kayak camping in the Everglades.
I've owned the K1, K2 (Twins), and currently own the KX3, PX3, KXPA 100 and KX2 ! I'm an Elecraft fan for life, I don't own and other brand !
Thanks so much Wayne for one of the best little radios, it's so simple and easy to use and just plain fun ! I wish I had ordered another kit now.
I'll never sell my KX1, I may even have it buried with me when the time come !

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return in 1 week to keep this great thing growing.

Today was indeed another good day as I worked 4 stations from my qth in Manitou Springs, CO.
I am running a K3 at 5 watts into an end fed half wave up about 30 feet.

I worked:
N5GW          GENE in Vicksburg, MS
WB8ICN.      MIKEY in Jackson, MI
WA5BDU     NICK in Russelville, AR
W4DBV.       DAVE in Old Hickory, TN

Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

I have two EFHW antennas. One covering 40 and 20; the other 17. They are 
mounted at about 40 feet and perform equal to regular dipoles.  Feeding 
them is therefore much simpler for portable ops since only one side 
needs to be elevated.  For portable use I feed them with about 20 feet 
of RG/58a, although they can be attached directly to the radio.  I find, 
however, that a bit of coax causes them to be a lot less finicky.  They 
have been my field day and SOTA portable goto antennas for many years.  
Transformers are not difficult to construct and there are some good 
quality assembled products that are excellent.

Brian,

If your end fed antenna is actually a halfwave (which is what EFHW 
means), the answer is no.

The solution for portable work is to use a length that is not a halfwave 
- 58 feet is known to work well for 40 thru 10 meters when used with a 
13 foot counterpoise.  Double the lengths if you want 80 meters.

With that antenna and counterpoise length, dispense with the balun for 
portable operations, and use a BNC to Binding post adapter instead (no 
coax).

If you need to use a short length of coax, you can put the balun at the 
end of the coax, and you can try both the 1:1 and 4:1 positions to see 
which provides the better match.

Don W3FPR

Don is correct.  I have the KFL3C-200 and it is marked on the filter itself.

-----Original Message-----
Stuart,

Look on the filter itself.  The offset should be marked on the paper tag
affixed to the filter.
I don't know about the new 6 pole filter, but that is true for the 5 pole
filters, and I assume it is the same for that one.

In other words, the offset is not on separate paperwork.

Here's the old trade-off between radiating efficiency and ease of 
matching for an end fed wire. The EFHW is more efficient, because little 
power goes into the ground system, but its high impedance is harder to 
match.  A wire of a different length may be easier to match, but more 
power goes into the ground system, where it doesn't radiate much.  Both 
will work but, I believe, on average the EFHW will be a bit better.  Is 
it worth the trouble?  Who knows?

Antenna discussions have long had a tendency to focus on SWR.  Low SWR 
does not necessarily mean an antenna is effective.  There's an old 
saying, "The SWR of a dummy load is 1:1."

On occasion I've run into RF in my KX3 when using a coax to feed random
length antenna. The symptom was that the radio wouldn't transmit with
anything other than trivial power, even though the tuner matched easily. A
quick choke wound out of the coax helped a little, but the Elecraft BL2
stopped the problem.

Personally I don't worry too much about the match when the radio is close
to the "antenna" if the tuner matches.

Mike, I find this a very curious belief. Do you want a schematic to know 
how the thing works, or how to repair it.

If you only want to know how the radio works, would a block diagram and 
a fairly detailed explanation from Wayne be enough (given they want to 
protect their design as much as possible)?

If you want to repair it, are you really skilled enough in soldering 
SMD's to do this? If so, my hat's off to you, sir! I've spent a lifetime 
working in the electronics industry and even in retirement I still enjoy 
restoring vintage electronics. But if I was faced with servicing a PCB 
full of SMD's, I'd say "Today my jurisdiction ends here"* and send it 
off to Elecraft for repair.

Just my $0.02, but you seem to be missing out on a wonderful rig by a 
questionable requirement. Put another way, do you also have a schematic 
for your microwave oven and cellphone?

Brian, W6FVI

Just a reminder, folks.

An End-Fed Half-Wave is a 1/2 wave antenna on the frequency of operation.

If it's not a half-wave, then it's a non-resonant wire.

Elecraft tuners do a great job tuning non-resonant wires.

They won't tune an End-Fed Half-Wave without some help, like a 9:1 un-un.

So, when someone says "EFHW" and then says "I just use an adapter and 
binding posts" we know it isn't an EFHW.

Terminology matters.

What I'd do if I was carrying it all on my back is take about 3 
different lengths of wire with banana plugs on end, and banana jacks on 
the other.

Use one as a counterpoise if needed.  Use one or two as the radiator, 
depending on how well it tunes.  You won't be using a resonant antenna 
because the KX2/KX3 won't tune it.

53' gets mentioned a lot as a good "random" wire length for most bands.  
I think the other two could be 8' and 15' since one would be a 
counterpoise, and the other would be used to change the overall length 
of the antenna itself -- that'd give you two steps.

Let me answer for myself. I want a schematic for both fixing it 
and learning how it works. I don't really think I will learn 
much about how it works from the schematic because most of how 
it works is in the firmware and not the hardware.

As for fixing things, I have made repairs to both my K3 and KX3. 
With Garry Surrency's help (Thanks!) and the schematics, I was 
able to trace a problem in my K3 that boiled down to a poorly 
connected TMP cable. No SMD involved. I do feel comptent to do 
some SMD work. When I did the power mod for the KPOD, I actually 
removed the old SMD resistor and replaced it. It felt more 
professional to do it that way than the other approaches offered 
in the mod kit directions.

On the KX3, I had a problem with the BNC antenna connector after 
it fell on the floor. The schematic showed me the details I had 
to work with to fix the problem.

As to the microwave, I replaced a fried component on the board 
without a schematic. It's been running the fix for over 10 
years. I don't remember how I found out what the replacement 
value was, but it was obvious from looking at the board.

No, I haven't cracked the case on my cell phone. It just works, 
although I saw a tool kit for opening it in the latest Jameco 
catalog. Maybe on my next order. :-)

I noticed in my N8XJK Boost Regulator that they had scraped the 
ID numbers off all the ICs. Now that's cheesy, and will make it 
harder to fix when both they and it are belly up.

I've never understood that:  Anyone with the knowledge and determination 
to trace out the circuit can certainly figure out what those parts are, 
functionally if not the precise part numbers.  Certainly, any competitor 
could do that, or they wouldn't be much competition.

I would run the single PTT to the ATU rather than the amp, and a single PTT line to the amp from the ATU.  The KAT500 needs to be able to break the PA key line to tune (switch small relays) at less than the full output of the PA.

Perfect explanation to help clarify all the "end fed" confusion.  Random is not EFHW!  EFHW must be cut at/very near frequency to work with a "tuned" matching circuit.  There's so much misinformation, with vendors also making good bucks on EFHW intereset.  Lots of "stuff" works but is it efficient? Do you get better radiation?  The efficiency of the end feds is too often left out of the conversation.  This created headaches for me as I began to study....  Screw it, I have a bunch of antennas ready to go and this includes both tuned EFHW, Randoms and dipoles, yet this evening while sitting in my basement hooked up the~30" 20 meter whip with 11' counterpoise. Heard some signals on a relatively dead band on my full outdoor antennas. Just like Wayne has suggested, try anything, anywhere. My most rewarding contacts have been on a walk about with the short vertical with a trailing wire and working SSB on 20 and 17.  God bless the KX2!

Just a reminder, folks.

An End-Fed Half-Wave is a 1/2 wave antenna on the frequency of operation.

If it's not a half-wave, then it's a non-resonant wire.

Elecraft tuners do a great job tuning non-resonant wires.

They won't tune an End-Fed Half-Wave without some help, like a 9:1 un-un.

So, when someone says "EFHW" and then says "I just use an adapter and binding posts" we know it isn't an EFHW.

Terminology matters.

Hi Don,
      I removed the 200Hz filter this morning, and as you said, the offset
was on the paper tag. I set up the -0.87 offset via the K3 utility, and now
all is well.

Thank you for your help, much appreciated.

Stuart,

Look on the filter itself.  The offset should be marked on the paper tag 
affixed to the filter.
I don't know about the new 6 pole filter, but that is true for the 5 
pole filters, and I assume it is the same for that one.

In other words, the offset is not on separate paperwork.

Message-ID: <AFCC8AA9-BA4A-43A5-BD44-56B61F10804E@va2ss.com>

Hi everyone,

I?m a fairly new K3S user since last November. I?m using with a lot of success and appreciation my K3S for digital modes, especially JT65 and JT9. I can actually do both without any issue.

But, I would like to experiment doing ? both ? at the same time by having a wider ? look ? at the audio spectrum using WSJT-X software. I actually have the 2.8kHz (position 3) and 6kHz (position 2) filters already installed and working perfectly in my K3S.

I can at the moment decode in a wide split view between JT65 and JT9 using the 6 kHz filter at the FLT position 2. It decodes as expected. But when it comes to transmit? not so successful for now. I can at the moment transmit for all stations below 2.5 kHz bandwidth where all JT65 stations are located. But when it comes to stations over 2.8 kHz? nothing?. no output? out of range? my filter setting is not properly set.

Must I set the ESSB ? on ? with a wider bandwidth if I would like to TX over 2.8 kHz ?? The K3S Utility stating that SSB and Digital modes both use 2.8 kHz for TX ??? I?m a little confused? :-) :-)

I now that it is something related to my filter setup?.. so if someone could just give me a hint, it will be much appreciated.

Use the *Split* features in WSJT-X.  See the WSJT-X help files

In essence, WSJT-X will adjust the transmit frequency (split)

A few years ago I replaced the stock fans on my K3 with the Noctua NF-A6x25 FLX fans and rubber mounts. ?The new ones are much quieter and the low rumble is gone.

Last night I got thinking about the fans and about the rumble of the stock ones.?
The question I now have is I wonder if the low rumble would be cured with just the use of the rubber mounts removing the need for new fans.

If someone is looking to quiet their fans wants to experiment with just replacing the mounting screws with the rubber mounts. ?I would be interested in knowing how much of a change they notice.

Message-ID: <CABYU7Wi2n2T3q8n0TrbH9uS7kn4rKONamiL-aXzdAuKVr4zvFg@mail.gmail.com>

Hi all,

I'm the proud (and slightly overwhelmed) owner of a KX3 station - the whole
smash.  I think I've managed to figure out SSB and CW, and now I'm trying
to work out the kinks in digital operations.

That's not what this post is about; this one is about communications.
When I launch HRD, or the KX3 Utility, I'm communicating with my KX3 at
38400 baud.   However, as soon as I add the KXPA100 in the mix, the speed
drops to 9600.  So, think I, the culprit is the KXPA100.  I check the
firmware and indeed it's not current.  So when I launch the firmware
updater, it reconnects to the KXPA100 at 38400.   When the firmware is
updated, it resets the amp and then communicates again at 9600.

So what gives?   I'd sure love to talk at 38400 all the time.  Is it a
restriction of the amp to KX3 interface?   I can't find any mention of it
in either manual.

Thanks in advance for any help/advice.

What?  I didn?t know that Elecraft offered frequency counters.  Or, do you mean something like the XG2, a signal source for testing rigs?

Frequency counters will also need to be calibrated. I have been 
quite happy using WWV with my K3, and you can't beat the price.

I am considering buying a frequency counter to calibrate my K3S.? I see that
Amazon has several for <$100.? Has anyone had any experience with these? 
Are they just a waste of money?

John,

You do not need a frequency counter to calibrate the K3S, use Method 2 
with WWV, it is just as accurate.
Actually it is likely more accurate than you would get with a <$100 
frequency counter, unless you calibrate the frequency counter 
beforehand.  I suspect any frequency counter costing less than $100 is 
either inaccurate or limited to audio frequencies.

Message-ID: <0D19106F-AF1D-4F86-8C52-3063A17E52BA@gmail.com>

This thread has really given me things to try when earth tilt/absence of white rain is back in our favour. Great group of folks on this forum btw. 

The many contributions to this thread have given me the confidence to try end feds (for the first time) on my up coming trip to HI9 land. I'm packing a few end fed lengths for whatever  the trees on the resort will support. I'll start with Wayne's 25ft radiator and 25 ft wire on the ground suggestion first. Again this untried for me. 

Before getting my kx3 I used an FT817 and the ATAS25. Worked fine when 20 to 10m openings were easier to come by a few years ago. Now my thoughts are about the reactions I'll get throwing something at a tree or two on the resort near the beach. I've managed to strip my CrankIR down to 12lbs so I'm taking it anyway only because I've used it/know it. The goal is to no longer feel the need to cram it into charter flight size and weight constraints and keep it for car trips instead. I'm guessing throwing a half full water bottle will suffice. Corrections invited. 

Now my thoughts are about permanent end fed resonant wires (vs dipoles) for the home shack. I currently have a home brew 80/40 centre fed dipole tied from the house to a tree in the woods. If that were instead an end fed resonant wire fed by a 9:1 at house end things could get much simpler (and less saggy) coax wise. 

Now comes the fantasy thinking... What about making it an end fed multi band by either putting traps in the 80m end fed or better still adding on a couple of fan EFHW wires for 40 and 20? Anyone tried this? How would the efficiencies compare to their centre fed trap or fan dipole counterparts respectively? 

Then there is that 160m antenna I'm think about putting up this summer...

Here's the old trade-off between radiating efficiency and ease of 
matching for an end fed wire. The EFHW is more efficient, because little 
power goes into the ground system, but its high impedance is harder to 
match.  A wire of a different length may be easier to match, but more 
power goes into the ground system, where it doesn't radiate much.  Both 
will work but, I believe, on average the EFHW will be a bit better.  Is 
it worth the trouble?  Who knows?

Antenna discussions have long had a tendency to focus on SWR.  Low SWR 
does not necessarily mean an antenna is effective.  There's an old 
saying, "The SWR of a dummy load is 1:1."

Some people seem to have a lot of trouble detecting "zero beat" but once the
technique is learned, it's easy to calibrate the K3/K3S to within 0.2 Hz of
WWV's carrier (one beat every 5 seconds). One could get closer depending
upon your patience.

It's useful to wait until WWV transmits a steady carrier with no tone,
otherwise it's easy to accidentally zero beat one of the sidebands produced
by the tone so you end up off by the frequency of the tone.

The K3 makes a great tunable frequency meter. Nowadays I use the K3
(calibrated against WWV) to check the calibration of the counter's master
oscillator.

Brian:

The end fed I use uses a stub for 20 meters. When I set it up I tuned the
antenna for 40 meters. Then I added the stub 1/2 down the antenna and
trimmed that for best SWR on 20 meters. Worked exactly as expected with an
antenna analyzer.

If you end up still wanting to get a frequency counter and want to spend a
few bucks, I would keep your eyes peeled for a good deal on an HP 5385A or
something similar on fleaBay, don't mess with the sub $100 cheap ones.
Then get a 10mhz GPSDO reference like the Leo Bodnar GPSDO
<http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=234>...
setup a simple GPS antenna outside your shack and then finalize the setup
with the K3EXREF.  Then distribute the 10mhz signal from the GPSDO to your
Frequency Counter and your K3.  You then end up with a lab grade accurate
frequency counter and you never need to worry about the K3 accuracy ever
again.   Then run out and get a frequency generator because you spent
several hundred bucks on the above setup and because the XG3 is just to
practical and simple... look for an HP 8656B or something similar and use
your GPSDO as a reference for that.  Oh and then you might want to get an
HP power meter like a E4418A and sensors to check the accuracy of the
frequency generator. (sensors at $150-$400 a pop) :)  Oh, and then if you
have a PPS output from your GPSDO you can setup your own Raspberry PI or
Odroid Stratum 1 NTPD server and have a NTP clock reference that is
accurate into the potentially nano second range to sync your PC clocks
against.  (all just because you can ... lol!)

Of course, I agree with the other posts... it's crazy simple to zero beat
with WWV and or switch back and forth between the CW side bands to zero
your REFCAL setting on the K3.  And it's free too. ;)  But some of us like
buying and tinkering with this stuff.  I'm guilty as accused.

Somehow the kxpa100 serial speed has been changed. Check the kxpa100 command reference to be sure, but try entering ^BRX3; followed by ^BRP3; in the KXPA utility command tester.  Then go back to the utility's port tab and click test communications. It should be 38400 at that point.

Firmware load is always done at 38400.

If your software supports 38400 I would recommend using that speed.

You can also use CHU for frequency standard calibration check depending on propagation.

Fan selection depends on a LOT of different factors....  rated fan speed
vs. voltage applied, CFM vs fan speed, dB vs. speed vs. CFM. Min/Max
current required, dimensions including thickness, type of bearing
system, etc, etc...
Ambient temperature....  Inlet restrictions, outlet restrictions,
internal obstructive flow....  thermal loading, etc etc...
Isolation mounts are simply one consideration.

BUT, anyone considering the replacement of stock fans should insure that
the replacement part supplies the same or more air volume at each speed
level.... unless you're planning to do a detailed study of your
operating condition to make sure the air delivered will accomplish the
thermal control required.

That won't work, because the shorter wires will present a much lower 
impedance, and essentially short out the half wave wire.  The whole idea 
of the EFHW is that the high feedpoint impedance reduces ground system 
current to practically zero.

A trap might work, but might not be compatible with keeping the antenna 
very light.  A QRP trap could be pretty small, I suppose, but it still 
might be hard to support the wire with the extra weight on it using a 
lightweight pole.

However, an EFHW will work on harmonics, though the pattern changes.  A 
40 meter half wave works quite well on 20, but I'm not sure an 80 meter 
half wave would be all that great on 20, especially with a single 
support.  The free space patterns of long wire antennas are shown in the 
ARRL Antenna Book.  As frequency goes up, more lobes appear in the 
pattern, and the main ones get closer to the axis of the wire.  For 
example, a full wave antenna has a cloverleaf pattern, the lobes about 
55 degrees from the wire axis, with nulls broadside.  For a 2 wavelength 
wire, there are 8 lobes, the main ones 35 degrees from the wire axis.  
These patterns will, of course, be modified by the effects of ground and 
the fact that the wire probably won't be straight, but the free space 
patterns give some idea of how the antenna will radiate.  Modeling these 
antennas is very easy, and gives much more accurate results.

Note that the pattern of an EFHW (full wave, etc.) is NOT the same as 
that of a center fed dipole operated at even harmonics.

It is my opinion that the K3s rates the use of a proper quality
frequency counter.
I bought a used, "lab grade" counter with an OXCO, and supply it with an
external GPSDO signal.

Is it required?  No, not really....

I initially calibrated the K3s with one of the government time
beacons...  not the simplest procedure that is often mentioned, but
requiring a few iterations...
Pretty confident that it was accurate to within 1-2 Hz...

Careful... calibration and precision can become quite addictive...  :)

As was said previously,  all end fed antennas are monopoles with displacement current flowing from the antenna element to earth. Unlike dipoles where the displacement currents flow from element to element.
So without an adequate radial system to reduce the ground loss all end Feds regardless of length are only about 10% efficient.
There are good reasons why 45 years ago when coax became readily available we switched from endfed monopoles to dipoles.

True, but that wasn't the point (and I think you understood that).

A wire that is approximately 67 feet long will be resonant on 20 
meters.  The impedance at the ends will be very high.

A wire that is approximately 80 feet will not be resonant on 20 meters, 
but an Elecraft tuner will be able to tune it pretty well.

My objection is calling any non-resonant length, fed from the end an 
EFHW (End-Fed Half-Wave), just because it kinda looks like one.

Correct.

Fan dipoles work because the resonant 1/4-wave elements are lower impedance than the non-resonant elements, so they get the majority of the power. A neat trick, really.

The LNR End-Fedz antennas use traps. They appear to work just fine.

For example, a full wave antenna has a cloverleaf pattern, the lobes about 55 degrees from the wire axis, with nulls broadside.  For a 2 wavelength wire, there are 8 lobes, the main ones 35 degrees from the wire axis.  These patterns will, of course, be modified by the effects of ground and the fact that the wire probably won't be straight, but the free space patterns give some idea of how the antenna will radiate.  Modeling these antennas is very easy, and gives much more accurate results.

Howdy Fellow Elcrafters:

Been reading the posts about fans for the K3.

So here?s my dumb question for the week.

Are there fans specifically designed to exhaust hot air from radios as opposed to fans that blow cool air into the radio?

Or is it simply a matter of turning the fan upside down to go from  ?blow in? to ?exhaust out???

Thanks for any info.

All efficient antenna systems are "resonant" (jX=0) but the shorthand often
used is "resonant" to mean "self resonant". That is true of any 1/4
wavelength long radiator (again our common shorthand is usually "1/4 wave
wire") or any multiple thereof worked against ground. It is also true of any
half wave length radiator or any multiple thereof. (Note that these are
electrical lengths, taking into account any surroundings including the
radiator itself.) 

While self-resonant antennas do not present a reactive load to the source of
RF power, the value of R, the resistance, may vary widely. There is nothing
magic about the 50 ohm load most of our transmitters are designed for. 

However, a half wave radiator fed at the center presents a resistive value
near 50 ohms when fed at typical heights above ground (in free space it is
75 ohms). Half wave antennas became very popular after WWII because 50-ohm
coaxial feed line became abundant and cheap on the "surplus" market and Hams
were taking steps to deal with needing to avoid interfering with the rapidly
growing number of TV sets in nearby homes, including the Ham's own living
room. 

In the following decades, greater and greater demands on harmonic
suppression have led to Ham transmitters with output filters specifically
designed for a 50 ohm load instead of being able to match a wide range of
load impedances. 

So we have now moved the wide-range output network that was in Grandpa's Ham
transmitter out of the transmitter and into what we call an "Antenna Tuner".
But, of course it does not "tune" an antenna at all. It's just a matching
network to be sure the transmitter is delivering power to a load close to 50
ohms and non-reactive.

Joe,

If the fan is to cool a large area like a heatsink, it is better to 
exhaust the air rather than blowing it in.
Only in the case of where the fan should blow onto a relatively small 
area would it be wise to direct the flow inward.
In the case of the K3, the fan should exhaust the air.

There is another subtle factor as well.  A fan creates "work" in moving 
the air and that "work" produces heat.  If you examine the temperature 
on the outbound side of a fan, it will be higher than the incoming 
airstream.  A principle of fluid dynamics that is not often considered.

Ray,

I think that is 'stretching' the facts a bit.
A halfwave dipole is a halfwave dipole whether fed at the center or at 
an end or somewhere in between.
The radiation pattern and efficiency is the same.
The problem is that an end fed resonant dipole does need a little bit of 
a counterpoise (0.05 wavelength) in order to be able to feed it properly.

Thanks, that was the ticket!   The one time that I had the PA off and the

I have an Elecraft K3S and a Heil PR10. I recently started getting complaints about my audio and may have inadvertently changed a setting on the radio.

With regard to this combination of mic and radio, where should I set the following:

Mic Gain Range - Low or High?

Mic Bias - On or Off?

Additional gain state - On or Off (elecraft manual says to turn on for very output low mics)

Thank you,

A dipole has two elements. An end-fed half-wave is a monopole. One element.

A half-wave antenna is still a half-wave, whether it is center fed (Hertz) or end fed (Marconi).

> ============

This is 100% correct. Two minutes spent with EZ-NEC will verify that the
radiation pattern of a dipole antenna is more or less independent of the
feedpoint location.The idea that an end-fed antenna is "less efficient" is
wrong. Antenna efficiency is a function of radiation resistance and ohmic
losses, not of feedpoint location.

The power has to go somewhere, and where it goes is into radiation. In the
days before most hams had an antenna simulator program, Cebik was a big
proponent of EFHW and had a nice analysis on his website. He made the
qualitative point that since the impedance at the end is high, there is
little current flowing in the unbalanced feedline at that point; if the
antenna is fed with open-wire line, the return current in the unterminated
leg is small and it's not hard to match. He followed this up with some
actual calculations. Although Mr. Cebik is no longer with us, nowadays
serious hams have antenna programs, so they can do their own analysis. The
role of folklore in antenna design has diminished considerably.

	gets louder
Message-ID: <CAFYRpHtA_81qKZ66Qp=yg9U18abdJ_a+x_tb=zkBXQJ1+=i_2A@mail.gmail.com>

I'm pulling my hair out on this one... all morning trying to do my due
diligence.

I picked up a used K3S which is like new... I got a great deal.  Anyway, I
verified with Elecraft that this K3S was factory assembled and there were
not any field upgrades installed based on the verification of the original
invoice with Elecraft.  All the goodies with the factory build are
installed.

The first thing I did when I got it was to reset all the settings back to
defaults and then take the time to go through setting everything up again
and running through all the calibrations etc...  It would have bugged me to
not know how everything was setup, plus I have done this many times over
the years with K3 kit builds etc...

My (new to me K3S) has the KRX3 installed and everything is working as
expected, except that I'm hearing the carrier-operated relay come on when
keying CW into a dummy load on ANT1.  I have verified that the KAT3A which
is installed to is not setup to send any RF input to the KRX3, but the
standard build is in place with the AUX RF BNC connector is connected
directly to the back of the KRX3 input.

I don't have a receive antenna hooked up to the AUX RF connector and in
fact I have put a dummy load on it just to be sure there shouldn't be any
funky RF getting into the KRX3.

I setup the CONFIG KRX3 setting to Ant=bnc and I have powered off the radio
and back on etc... but I still get the problem with the carrier-operated
relay coming on.  There is some info in the manual about an issue with VCO
CAL needing to be run again if you have this issue, but I don't believe VCO
CAL applies for the K3S with the new synth boards.

I have a solid dummy load connected to ANT1 and I just can't see what would
be causing the carrier-operated relay to start to switch on as increase
 power to the +12 watts point where the KPA3A kicks in.  I can start to
hear the relay to start switching around 20 watts plus as already mentioned.

Hmmmm, any thoughts... hope someone made it this far into the post.  I hope
I'm not having an RTFM or STFI moment here and missing something obvious.

Fan selection depends on a LOT of different factors....? rated fan speed
vs. voltage applied, CFM vs fan speed, dB vs. speed vs. CFM. Min/Max
current required, dimensions including thickness, type of bearing
system, etc, etc...
Ambient temperature....? Inlet restrictions, outlet restrictions,
internal obstructive flow....? thermal loading, etc etc...
Isolation mounts are simply one consideration.

BUT, anyone considering the replacement of stock fans should insure that
the replacement part supplies the same or more air volume at each speed
level.... unless you're planning to do a detailed study of your
operating condition to make sure the air delivered will accomplish the
thermal control required.

The next time I experiment with end fed antennas, I want to try 
a matching transformer at the end of the antenna wire of about a 
50:1 matching ratio. That way I will have an impedance in the 
feed line of about 50 ohms and minimize coax loss. Now if I am 
connecting the antenna directly to binding posts on the side of 
the KX(2/3), the loss won't matter. But if I am using a length 
of RG174 for a light weight feed line, the lower loss will be 
very nice.

Adding Don's recommended 0.05 wave length "counterpose" in the 
binding post scenario sounds useful. With a coax feed, the coax 
should perform that function.

Now, where am I all wet?

It would appear you made a good choice in fan selection....  FYI, I use
sorbothane for isolators and other damping needs.  Works great.  Noise
reduction depends on making sure to interrupt the connection between the
fan body and the mounting point in the case.... to include not letting
the same fastener touch both the solid fan chassis and the radio
chassis, etc. Next is to prevent airflow short circuits... et al.

The additional 10mm of case thickness doesn't interfere with anything?

That's a common misconception, especially among those of us who have spent
time working with center fed dipoles. 

The "poles" refer to the voltage nodes, not the number of elements. A
dipole, having a voltage node at each end, is a di(two)pole radiator, while
a quarter wave antenna, having only one voltage node is a mono(single)pole.

A dipole has two elements. An end-fed half-wave is a monopole. One element.

A half-wave antenna is still a half-wave, whether it is center fed (Hertz)
or end fed (Marconi).

You're close, Bill.  The short counterpoise should go at the antenna end 
of the feedline by the transformer, not at the radio.  It probably won't 
make much difference, though, as the outside of the coax will serve as a 
counterpoise.

Depending on the design of the transformer, its inductance and stray 
capacitance may have some effect.  The inductance will affect the lower 
frequencies, where it appears in parallel with the antenna.  You can 
compensate for that by making the antenna a bit longer.  On the higher 
bands, the stray capacitance may require the antenna to be slightly 
shorter than a half wave multiple.  (I hope I got that straight.)  In 
any case, if you can't match it, experiment with the wire length and see 
if you can find one length that will work on all the bands you need.  
I'd be interested in hearing the results.  A single EFHW (multiple) and 
transformer that can be used with an internal ATU alone on 80-10 meters 
would be very attractive.  (Or even up to 15 or 20 meters.)

Note that a 50:1 transformer has a turns ratio of about 7:1.

Bill, you are close to the famous Zeppelin antenna. It was a
single-frequency antenna. The idea was to move the RF field as far as
practical from the airframe. RF arcs between elements of the duraluminum
airframe were to be avoided, especially up near the top of the airship where
there was always some leaking hydrogen finding its way out through the top
vents on the covering. 

The original antenna was 1/2 wavelength long and fed at one end by 1/4
wavelength of open wire line. At the antenna end, one of the two wires in
the transmission line was connected to the 1/2 wavelength long radiator. The
other wire terminated at an insulator, and nothing else. 

Since the 1/2 wavelength radiator presented a very high impedance to the
feed line, very little current flowed in that side of the feed line into the
antenna. Since the other side of the feed line went to an insulator, there
was very little current flowing there too (some current would result from
typical leakage at the insulator). The end result was decent current balance
and minimum radiation from the feed line from the balanced output of the
transmitter to the actual connection to the radiator. Since the feed line
was electrically 1/4 wavelength long, the very high impedance at the antenna
was transformed into a very low impedance at the transmitter. 

The weakness in your design will be the transformer. Even at QRP levels,
very high voltages can occur at the end of a half-wave radiator and so in
your transformer. It's pretty easy to build an open wire line to handle the
voltages without voltage breakdown. Not so easy in a transformer.

No, end fed halfwaves are not dipoles. They are monopoles. Take a look at the ARRL antenna book, LaPort, Johnson or any of the classic antenna books.  There is a reason why all the AM broadcast Stations with  halfwave end fed antennas have radial systems that consist of 120 radials that are 0.4 wavelengths long. Look at the licenses for KRLD, WIP etc.  they can be found on fccinfo.com. I don't think KRLD would have spent over 200,000$ replacing their ground system If end fed half wave antennas were dipoles and did not need a radial system to be efficient radiators.
The best way to picture an antenna (ARRL Antenna book) is as a capacitor with displacement current flowing between the plates.  With a dipole each of the plates is a antenna element.  With a monopole, one plate is the radiator and the other plate is ground.  Since even good ground is a poor conductor, a large resistor has been inserted in the circuit.  The radial system acts to reduce that loss resistance and increase the power radiated.

Here is what Heil says:

We highly suggest our dynamic element microphones (HC-7, HC-5.1 , HC-6, Goldline GM series or PR-781 type). In this case, while setting up the MAIN: MIC SEL menu, tap [I] to toggle to "LOW" Mic Gain, and be absolutely certain that Mic Bias is off by tapping [2], as needed, to toggle to "OFF" for Mic Bias.
If you are using our high output "iC" element (Pro Set iC, Pro set Plus iC, Pro Set Elite iC, Handi Mic iC, or the iCM via the HSTA-K8 adapter cable), tap [1] to select "HIGH" Mic Gain, and tap [2] to set the Mic Bias to the "ON" option. Keep in mind this will have much more output and 'may' overdrive the mic preamp so keep ALC in range.

It's been a couple of years since I put them in, they come with a 3 pin connector instead of a stock 2 pin connector.

As I recall I clipped the third wire (yellow wire) and then trimmed the connector down to 2 pins (red and black).

If you search the messages archive I believe someone listed the part numbers for the 2 pin connector ?if you want t go that route.

I can confirm that both a friend and I have fitted Noctua fans to our 1,000

assortment of connectors and were very easy to fit, but you have to get used
to their different colour Hi Hi!  They appear to be high quality and we
don't regret making the change.

 

As an aside, I had an Icom 820H that used to shut down because its heatsink
overheated during ragchews.  I replaced its fan with a Noctua and the
problem was solved.

 

Although Noctua is an Austrian Company, the fans are made in Taiwan.  At
least, it's a change from China Hi!

Subject: [Elecraft] [OT] end-fed halfwave antennas
Message-ID: <CAHmQzT=Yj4QTOeBirxQQ1C=EEGEihaiZX6ZVt+wBd77nqxf+hA@mail.gmail.com>

My Elecraft rigs are connected to guyed, end-fed half wave vertical
monopole antennas, one each on 30 meters and 40 meters.  I use
tapped-L-parallel-C matching networks at the base of these antennas, which
are ground mounted and insulated.

They radiate at the horizon, or darned close to it, and don't need any
inconvenient ground radial wires, or even a particularly low impedance
earth.  To me, that fact alone was worth any other effort.

I got inspiration for my antennas from similar designs used at the
following addresses ... each have historical markers, incidentally ... if
you are curious, you can use Google Maps to see them yourself:

764 Tylersville Road, Mason, Ohio

8068 Concord Road, Brentwood, Tennessee

While the hams who designed and installed these antennas had bigger budgets
than I do, they had the same goals.

For portable use, if you can manage an overhead tree branch at a suitable
height, only 60 feet of wire interrupted in the center with 47 microHenrys
of L yielded a center-loaded EFHW I used *very* successfully on 80 meters.
Again, no radials needed, a major consideration to me.  The feedpoint
impedance was quite high, so the matching network I had to make was
interesting but still do-able.

I think about the only real solution for the fan noise on the KPA500 is to remote it.

On the subject of quieter fans, any thoughts on a quieter fan for the 
amp? I do a lot of AM and a quieter fan would be nice - else the amp 
will get relocated to a different location in the shack.

Tom,

Unless I read the K3 and K3S manual incorrectly, Heil has the "HIGH" and 
"LOW" mic gain settings reversed.

The HIGH and LOW settings refer to the mic gain, and not to the 
microphone output.  Those Heil mics have very low output and should use 
the HIGH mic gain setting.

Bill,

Have you considered (or already done) setting the minimum fan speed to 2 (or
3)? Doing this helps delay the onset of higher fan speeds. Of course, long
duration AM transmissions this may not help, but I have notice it help on
lower duty-cycle modes.

I just lay a soft bladed fan on the top grill to pull air up. its run by a

WAY quieter than the back fan, because it never comes on.  It?s a silicone

Don,
You may be correct.  Fred in his book recommends High for Heil mics, both
electrek and dynamic where as Heil only recommends High for the electrek.

I would have thought if the Heil site was wrong someone would have noticed
it by now and Heil would have changed it.

I also thought the Heil electrek mics were high output so find it strange
that they would not require a low setting.

Tom,

Yes, the electret mics typically have high output levels and thus can 
use the low mic gain setting.

In other words, the Heil website has it "backwards".  I am not sure Heil 
will be willing to change it.

Something isn?t racking then because Fred in his K3s book recommends high for the electrek mic. ?Per Fred and Heil?s recommendation I am using a Heil BM-10ic and have the radio set to High with bias and I get good audio reports.

Tom,

I don't know about the Heil Electret mics, but in my experience with the 
K2, the electret mic output from the Heil "iC" microphones is equal to 
that from most other electret microphones such as the Elecraft MH2.

Perhaps Heil has reduced the output of their more recent electret 
microphones, I just don't know about that because I have not had recent 
encounters with them.

Tom,
I would use whatever setting works the best; if you are receiving good audio reports, "leave sleeping dogs lie". ?If your mic gain is set at something reasonable (mine is "9"), I wouldn't worry about what is "suggested". ?Too many variables with your voice characteristics; if you are calling a "P5" for an ATNO, you might be speaking a bit louder than working a JA for the 300th time.

The real bottom line is to use the indication on the K3 (K3S, KX3 and 
KX2) ALC meter.
If you are driving the voice audio up to the 5 to 7 bars level, that is 
correct.  If it is going higher reduce the MIC gain or switch to the low 
mic gain setting.

If it is lower than the 5 to 7 bars, increase the mic gain or switch to 
the high mic gain range.

It is with some reluctance that I smack this whole EFHW tarbaby, but here goes.  
Comments in no particular order:

1)  A resonant antenna (even one that is self-resonant), e.g. one with a 
non-reactive feedpoint, isn't necessarily "efficient."  A quarter-wavelength 
monopole over lossy earth leaps to mind.

2)  A non-resonant antenna isn't necessarily inefficient.  The ever popular G5RV 
isn't resonant on the band of interest (20M) but when fed appropriately, was as 
efficient as a resonant dipole.

3)  Consider a BC band 1/2 wavelength vertical antenna.  Does the station 
designer say, "Well, this EFHW doesn't really doesn't need much of a 
counterpoise, so I'll just throw a 100' long wire on the ground and call it good 
enough?"  No, he install 120 radials that are even longer than the ones he would 
use under a 1/4 wavelength monopole.  Devoldere in "Low-Band DXing, Chapter 9, 
Section 4.3 says: "Here comes another surprise. A terrible misconception about 
voltage-fed verticals is that they do not require either a good ground or an 
extensive radial system.'"  Later in the same section he says, "Therefore it is 
even more important to have a good radial system with a voltage-fed antenna such 
as the voltage-fed T or a ?/2 vertical. These verticals require longer radials 
to do their job efficiently compared to current-fed verticals."

3)  When you backpacking mountain goats say, "Hey my wire isn't a vertical, it's 
mostly horizontal", I say, if your radio is sitting on a boulder or the ground, 
it's a vertical and your wire-on-the-ground counterpoise proves it.

Ha, ha!!! Well put Wes! 

Some mountain portables erect low "horizontal" antennas on the side of a steep mountain. The result is a very low angle of radiation because, even though the main lobe is "straight up" from the mountainside from the antenna, the slope puts that lobe at a fairly low angle relative to the earth.

I figured out what was going on here...  I'm assuming that the carrier
sense relay is only on the new KAT3A?, and in this case, it helped me solve
an RFI issue in my shack.  I was powering a receive antenna pre-amp and a
10mhz reference signal distribution box with the same PS as I was using for
the K3S.  Not a great idea where both devices in this case had outputs
(obviously) back into the K3S.  i.e. the RX antenna input and the K3EXREF
input from my 10mhz reference.  Sigh... it has been a long day gyrating
around with things... removed all the ground connections to everything and
as luck would have it... the light finally turned on with the PS powering
the two boxes mentioned above.

Don,
Can't argue with the advice in your email; in fact, I think the best response I have read.
As for "how you sound" on the other end, one setting no one mentioned is transmitter equalizer settings. ?I could be wrong, but from what I remember, Heil used to sell mics with a freq response tailored to communications. ?Now, with all the new rigs having the ability to adjust the frequency response to match your voice, the new mics are wide range (pro 10 specs are, "Producing full articulate sound from 85Hz to 16kHz". ? Now, you can adjust the freq response of your rig to match your voice.
Having said the above, I have to admit I haven't "played" with the equalizer, so my settings are 0 dB across the board. ?Might be interesting to hear from a few of you that have made changes, how you evaluated your changes, and (in the long run) have you found it made any difference. ? Additionally, I would think what your interests are, will affect what settings you find work the best (DXing or ragchewing).

?So what we are saying here is that all the local and DX QSOs we make from
a picnic bench with an end fed or random wire thrown up in a tree and a
short or no counterpoise doesn't really happen or, at best, is a fluke. The
end fed is only 10% efficient (did I get that right) and most of our QRP
signals are going to heat worms. Pretty hopeless situation I guess. ?I
might have to just stick with the local repeater and Google Hangouts for
communications.

Or, for those of you that are thinking the situation isn't so hopeless,
grab your portable antenna, head out to the campsite, throw your wire up in
the tree and I'll catch you on the air. Let's warm up the worms.

A certain inductance places at a correct place along the 80m HW will 
make multy band EFHW. Here is the example

I'm pretty sure the laws of physics are still in place.

What you describe isn't much different from my situation on 160 meters.  I have 
an inverted vee dipole with the apex at 45' and the ends at 6 feet or less.  
With 500W I have worked about 60 counties.  But I am under no illusions that 
this is an effective antenna; it is not.

Several years ago on a Field Day when the locals were all on mountain tops 
calling CQ and not listening, I worked a JA using the same antenna, at that time 
still fed with 200 feet of RG8 (now Heliax) and a barefoot K3 with no ATU. An 
hour later I worked a second JA.  But do I recommend this setup for working 6 
meter DX? Of course not.

So you make some contacts.  Good for you, maybe you're having fun.  However, I 
submit that you (and I) would have more fun with better antennas.

10% efficient is for a ?short? end fed antenna and a ground rod or similar.
Something near a quarter wave and a typical one or two wire counterpoise is much better.
It doesn?t take much effort to get to 50% efficient with a quarter wave or longer wire, and a few short radials.
After that, there are diminishing returns for a given amount of effort.  The BC 120 radial, half wave long ground systems are a good example.  
And, as QRP and mobile operators have shown, contacts with a 10% efficient antenna system do happen!

Absolutely! I had fun as a kid with antennas at about 25 ft in the maple 
trees at the front and back of our lot. I had fun with dipoles strung 
between telephone pole in the alley and the front of my apartment in 
Chicago, and somewhat better dipoles on a house I later owned in 
Chicago. I've worked DX with 5W into a wire taped to a fiberglass pole 
and jammed into a picnic bench, with a counterpoise laying on the 
ground. I now have an antenna farm beyond my wildest dreams, and I'm 
having even more fun. I can testify that better is better. :)

I'd have to total it up, but I probably made close to 1,000 contacts 
with an  EFHW and KX1 last year.  The whole antenna system, including 
the 38 foot fishing pole and tuner, weighs about 1.5 pounds.  Of course, 
it doesn't work as well as a high, full-sized antenna, but if anyone can 
come up with one that works better and doesn't weigh more, I'd like to 
hear about it!

Good Evening,

    Propagation has gotten slightly better.  A little is from the noise 
level dropping and some from the sun moving northward.  I have not had 
much chance to get on the air since last weekend. The power stuttered 
moments after the second net and went out for three days an hour later.

Weather has been hectic since last weekend.  First 20" of snow falls 
then heavy rains melt it again.  Luckily the flooding was not too bad.  
I keep walking the forest and finding more work to do.  Lots of damage 
but it does direct my thinning.  There is now a gap close to 1/8 mile 
long.  A Beverage antenna running due north?  Or the first leg of a 1/2 
mile loop?

Please join us tomorrow on:

    14050 kHz at 2300z Sunday (3 PM PST Sunday)
      7045 kHz at 0100z Monday (5 PM PST Sunday)

Just picked up a couple of toroids at a swap and want to make an earchi
antenna for the kx1. As I want to take this backpacking the plan is to
connect directly to the radio and use a counterpoise instead of using coax
in order to save weight. Has anybody found the secret length for the antenna
to tune 20-80? How about counterpoise length? I did see a post that
suggested that over .05 wl on the counterpoise for an EFHW didn't yield much
improvement on performance. 

Just wanting to keep things as light as possible. Not even sure if I will
use a case for the toroid, maybe just a pigtail with a bnc on it.

The EFHW antenna was not invented by anyone alive today. It is very
definitely a classic antenna. It's just a very efficient antenna that has
gone through periods of forgotten usefulness.

An end-fed 80m half wave L, or other "bent" form, is an antenna that has
been used successfully at least since 1957 when I first saw one as a 14
year old. The at-the-time 52 year old AM BC chief engineer who explained it
to me, alas, is long gone. He would be 111 today.  No one used center
loading coils back then. Puts the max current in the antenna on the loading
coil. If you couldn't make it long enough, you made it long as you could
and the difference got soaked up in the matching network.

Hams seem irresistibly drawn to antennas where "matching the antenna"
consists of connecting it directly to a piece of coax.

So it is that over the years, especially on 80m, many have shown up on the
air with amazingly inefficient antennas on 80m. They would check into 80m
traffic nets with really puny signals. Many of these weak signals were
excellently solved by going to an end-fed halfwave L fed with a matching
network (usually a tapped coil in parallel with a capacitor) against some
horrible ground. Grounds like a couple of buried bare wires running away
from a basement window, or even a ground rod, did not matter in series with
the end-feds' feed Z's in the 1000, 2000 ohm range and up.

The improvement in signal strength converting to the EFHWL was often
remarkable, as in two or three S units, or as said back then, "gone from a
peep to a pounder".

The EFHWL has never been popular because it always requires a matching
device *at the base of the wire*, and without some remote switching of taps
and/or cap value, only covered 50-100 kHz of the band in today's common SWR
limits. However back then that was often extended as rigs with tetrode tube
finals were far more tolerant of antenna Z. At QRP, particularly among the
SOTA and backpacker crowd, the EFHW is making a comeback.

If we ever get a good manufactured off-the-shelf *QRO* end-fed tuner, the
80m EFHWL will get popular and stay that way.

Try about 12 feet of RG-174 between your rig and your earchi transformer.
That will make your .05 wl counterpoise for 80m without much weight and
without much loss on the higher frequency bands.

Hi John,

This is great! Thank you for taking the time to write this. 

Having only experimented with centre fed dipoles as base antennas over the years these end feds open up a whole new set of placement possibilities for me. I have to confess prior to this I thought of (random wire) end feds as non resonant compromise antennas. Yet another shattered paradigm for me.  

Come spring I will in fact be trying these out in place of my current dipole. I'll source and order the torriod cores now and I will surely keep you posted. Also I think a 160m end fed will be a worthy project this summer. 

So height above ground of the end feds will have the same effect on take off angle as it does with dipoles?

My What3words locator is unclip.weirder.shields if you want to check out my property layout on google earth. 

Thanks and regards,

Brian ve3bwp

Brian,

I repeat what I have posted several times:
A resonant dipole radiates the same no matter where it is fed - center, 
end or anywhere in between makes no difference in the radiation pattern.

In other words, a dipole is a dipole, is a dipole.
The dipole refers to the current/voltage distribution, and not to how it 
is fed.

Chip,

A length of wire is much lighter than any coax, including RG-174.
Important for those backpacking.

I've done a lot of backpacking, and used a fair amount of RG-174. 12 or 13
feet of that weighs very little - about 13 grams or 1/2 oz., and would add
to flexibility of antenna placement too.
Thats my experience anyway.

Yes, if you can feed power to it.

I don't understand all the innuendo about what works when some numbers 
can put things into perspective.

Here are some EZNEC numbers.  A 33' (1/2 wave on 20) wire on 20M with 
one end at 2' and the other at 25'

Feedpoint % from end    Z           SWR
1.2                    2445-9196j   >100
6                      746 -919j     39
11                     301 -342j     14
15                     230 -175j      7

This strongly indicates that some counterpoise of about 10% above the 
ground (remainder of 33' in air) should be used to bring the Z down to 
reasonable values for matching.  Regardless, there will be a large 
complex value of Z to null out.

It is really unfortunate that advice like this continues to be...excuse the

information to the contrary freely available on the Internet and/or in books in 
your local library.

I have already quoted one source but I'll do it again for emphasis. (Hopefully, 
the formatting will survive)

  Devoldere in "Low-Band DXing", Chapter 9 says:

        Here comes another surprise. A terrible misconception
        about voltage-fed verticals is that they do not require either a
        good ground or an extensive radial system.

        4.3.1. The Near Field
        If you measure the current going into the ground at the
        base of a ?/2 vertical, the current will be very low (theoretically
        zero). With ?/4 and shorter verticals, the current in the radials
        increases in value as you get closer to the base of the vertical.
        That?s why, for a given amount of radial wire, it is better to
        use many short radials than just a few long ones.
        With voltage-fed antennas, however, the earth current
        will increase as you move away from the vertical. Brown
        (Ref 7997) calculated that the highest current density exists
        at approximately 0.35 ? from the base of the voltage-fed
        ?/2 vertical. Therefore it is even more important to have a good
        radial system with a voltage-fed antenna such as the voltage-fed
        T or a ?/2 vertical. These verticals require longer radials
        to do their job efficiently compared to current-fed verticals.

Another invaluable source is Rudy Severns, http://www.antennasbyn6lf.com/ Rudy's 
work is meticulously measured, beautifully documented and presented.  He has 
written many articles for QEX, which are available on his site or via an 
Internet search.

==========
No, that's not right. The radiation pattern and gain of an end-fed halfwave
are little different from a center-fed dipole. The efficiency of an antenna
is not affected by feedpoint location. The end-fed antenna may be harder to
match than a center-fed, but that's a different question. If you have a
proper matching arrangement between the antenna's high impedance and your
feedline, you'll get results that are essentially identical to a standard
doublet. As I mentioned in an earlier post, two minutes with EZNEC will
clarify this.

"Efficiency" refers to the quotient of the antenna's radiation resistance,
divided by ohmic losses. If you have a short piece of wire, its radiation
resistance will be low, but for a half-wave wire it's 73 ohms, no matter
where it's fed.

As a side-note, I worked over 300 countries with a 100-foot wire strung out
my bedroom window (16 feet above the driveway) and running to a tree at the
end of the yard, 40 feet high at the far end. There's a picture of it on my
qrz.com page.

I purposely overlooked the obvious error that broadcast band antennas are 1/2 wave length long. How many BCB stations has anyone seen with a free-standing transmitting tower between 400 and 1000 feet high?

Most BCB (0.5 to 1.6 MHz) antennas are 1/8 wavelength high (or less) which necessitates an extensive ground system. Even so an efficiency of 10% or less is not surprising. 

A half wave radiator a decent distance from the earth is much, much more efficient, no matter how it is fed (end, center, off-center).

10% efficient is for a ?short? end fed antenna and a ground rod or similar.
Something near a quarter wave and a typical one or two wire counterpoise is much better.
It doesn?t take much effort to get to 50% efficient with a quarter wave or longer wire, and a few short radials.
After that, there are diminishing returns for a given amount of effort.  The BC 120 radial, half wave long ground systems are a good example.  
And, as QRP and mobile operators have shown, contacts with a 10% efficient antenna system do happen!

Alas, if only this was true.

Google "radial system design and efficiency in hf verticals" and you should get 
a cached version of Rudy Severns' paper of the same name.  In it he states:

"Alternately we can graph efficiency in terms of Ga as shown in figures 3 and 4. 
Unfortunately this also shows how inefficient verticals are even over very good 
ground. Very depressing! For example, with very good soil (0.02/30) and 128 
1/2-wave radials, the efficiency of a 1/4-wave vertical is still only -2.76 dB 
(53%)!"

Slip up at this end, I didn't send it to the list.

And whilst I'm resending I might as well mention that I am using the Leo 
Bodnar GPSDO to drive the REF IN port on my K3. I have found that the 
unit locks up within 30-45 seconds from power up with the antenna in the 
shack, near the north facing window with a clear half hemisphere view.

Totally unnecessary for general HF operation but having driven a 
commercial Intelsat standard B 11 metre dish earth station with all the 
necessary test equipment you can become a bit anal about this stuff.

So for the second time:

The "Method 2" using WWV is fine, however, there is a slight gotcha.

I have the 1ppm TCXO in my K3 and have been using WWV since new (#1400). 
Checking the REF CAL regularly I've noticed the setting changes slightly 
each time, ageing of the TXCO I was thinking, there will be some truth 
in this but it isn't the whole story and once I started using the 10MHz 
ref-lock feature fed from a GPSDO reference a whole new story emerged 
from monitoring the change in the REF CAL parameter, the TCXO frequency.

My TCXO will drift HF approx 28Hz within the first four minutes after 
switch on, perfectly reasonable. It will then plateau for about 26 
minutes and thereafter start to drift a further 27Hz HF for the next 90 
minutes. For the next two hours it will drift HF another 5Hz and stop.

All the time whilst this drift is taking place the front panel is 
heating up, mine is fitted with the sub RX DSP board so fully loaded. On 
RX only the temp changes from 23C at switch on to 40C over the four 
hours. The bulk of this temperature change taking place in the first 
hour, only a few degrees there after.

I suspect that on RX the front panel is the main source of heat within 
the box and over time is the main factor contributing to TCXO drift.

I observed that TXCO drift is not translated directly Hz for Hz to 
calibration accuracy. I did check it on 28MHz and and found that cal 
drift was approximately half that of TXCO drift. Wayne will know the truth.

So from all this I would suggest that a one to two hour warm up before 
doing a REF CAL using WWV might be a good idea.

Using WWV you can do your own TXCO drift measurements. Just do a "Method 
2" REF CAL as soon as possible after switch on and again at 30 minute 
intervals for the next couple of hours making a note of the REF CAL 
readings as you zero beat WWV. Armed with that info you can set the REF 
CAL to a number which indicates a good stability has been reached.

I'm not saying all K3(S) will have the same drift pattern as #1400. My 
TXCO is well within the 1ppm spec and if the first four minutes is 
discounted it is nearer 0.5ppm which has been reported as typical and 
hence no need for a "Method 3".

Clearly checking the REF CAL at random times after power up will give 
varying set points. This is what has made me offer previously that 
setting REF CAL is not a one off deal. Given a bit of ageing of the TCXO 
then maybe it is over a sensible time scale of a couple or more of years.

Mike VP8NO

Wes,

I do not doubt what you are saying about 1/2 wave verticals, but most 
EFHW antennas are mounted as a sloper or a horizontal antenna.

For portable operation, the main concern is for the ability to feed the 
antenna, and not about maximizing the far field strength.

Dan's original post concerned the effectiveness and practicality 
of various EFHW configurations in a man pack environment. 
Since he had already decided that his radiating element will 
be 1/2 wavelength long, the primary concern is power transfer 
efficiency vs. practicality of the solution in a weight and space 
constrained man pack environment. 


For the entire history of radio, RF ammeters have been used to 
evaluate the efficiency of alternative matching systems and their 
associated radial/counterpoise systems. An RF ammeter could 
be placed in Dan's EFHW antenna -- ideally in the center -- to 
compare the relative performance of practical man pack EFHW 
implementations.

Noctua fans are very popular in the computer enthusiast market because 
they move the same or better cubic feet per minute with significantly 
less noise. They are more expensive. When you buy a $5 fan...you get a 
$5 fan.

I just built a new computer. Two intake fans down low blowing cool air 
in the case, two exhaust fans up top blowing hot air (relatively) out. 
Most people don't know the direction of air flow when looking at a fan 
like these. If you see the label the air is blowing toward you, if you 
don't the air is blowing away,

The fans on my processor and video card suck air through the heat sinks 
and out. The fan in my 800W power supply sucks air through the power 
supply and out the top.

Subject: [Elecraft] KX3/PX3/KXPA100 - PX3 taking 5 minutes to come on???
 KXPA100 loses mind...
Message-ID: <89b12825-6dbc-dcb3-7ae6-9c86cff14471@frawg.org>

All, (particularly Don or one of the kind folks at Elecraft support)

There are two seemingly interrelated problems in this message that may 
indeed be independent.

    All other helpful souls - before you post an answer, please read
    this ENTIRE message. I am a tech type and no stranger to radio -
    computer control systems. I did check cabling to make sure it is OK,
    an solidly seated. Firmware is updated and I configured all devices
    from factory settings.

My trusty KX3/PX3/KXPA100 kit has been on the shelf for an all too long 
respite because the antenna farm was one tree short. It is going back 
into regular service alongside an ICOM 7300 now before I build field day 
and trail "go kits" for my beloved KX3 system. Since it takes about 2 
hours to get everything behaving here - this is going to be a lousy 
EMCOMM and Field Day solution... For the trail, it doesn't matter 
because the KX3 goes alone.

Here goes: As I was bringing things back online today, I found a 
stickynote to self about an issue I had with the PX3 and the KXPA100 
before I stopped using the kit in December. I am still observing the 
following behavior:

When the PX3 is powered on "cold", it takes about 5 minutes for the 
display to light up.

    This occurs regardless of the power on jumper position which is
    currently back in the enable (pin3/4) position.

    This occurs whether the KX3 or the KXPA100 are cabled in.

    Once the PX3 is "warm". I can turn it off and then on again and it
    comes right back to life.

During this PX3 "braindead" period, when the entire setup was cabled up, 
the amplifier will not work properly. To make things more annoying, 
after the 5 minute braindead spell is over and the PX3 is working and if 
the KXPA100 decides to cooperate, I have to go back into the menu, 
enable the KXPA100, then reset the power level for the whole system 
every time this happens... but the PA does not always stay on!!! Then I 
have to tweak the whole system until it decides to work... when the 
KXPA100 is enabled by the KX3 menu, it holds PA MODE ON a moment and 
then reverts to PA MODE OFF without my doing anything.

Today in desperation, I tore everything down and re-connected several 
times and FINALLY all 3 unit talked to each other and the PA stayed on.

This started occurring in the fall of 2016 (September or so), I do not 
recall that any of this happened when I first assembled the PX3 and 
began to use the KXPA100.

So before the inevitable deluge of helpful "Did'ja look" comments come - 
current firmware is :

KX3 is at MCU version 2.38, DSP is at 1.37

PX3 is at MCU revision 1.39

KXPA100 is at revision 1.39

AND ALL units are set for 38,400 and communicate with the computer.

All cables have been checked and are properly seated.

Thanks in advance for your help!

Don,

As I said earlier in this thread, if the radio is on the ground, or near the 
ground, then the antenna is a vertical.  I don't care what the slope is, it has 
a vertical component.  A Beverage is a horizontal wire, but it is vertically 
polarized and works against ground.  It may be lousy ground (which is actually 
required) but nevertheless there is a connection to earth.

I think the fallacy here is that folks believe that a 1/4 wave wire, which 
wouldn't have such an intractable feedpoint impedance, requires "ground" and an 
EFHW doesn't.

Now if the battery-powered radio is dangling above the earth at the end of a 
horizontal wire and the keying is via Bluetooth I guess there is some ground 
independence.  But in that case I would recommend putting the radio in the 
middle of the wire and saving some grief.  Likewise, if you want to fool with a 
Zepp feed why not use center feed?

If maximizing far field strength is of no concern then I recommend a 50 Ohm load 
on the output of the radio :-)  You could crank the power down to save the 
battery and it would have no effect whatsoever on the signal strength at the 
receiving end.  A win-win!

For me a large part of the enjoyment of Amateur radio is the process of building the radios and accessories.

I tend to like kits because all the truly hard work making the board punching and painting the case etc has been done for me and I get the fun of building it and then using something that I have built.

I would love to see an updated version of the K2 as a full kit, but that leaves me wondering is there really a market for full kits?

I was curious as to what others think about the market for full kit radios.

Hey Harry... I hope you don't mind if I toss another idea out there. It has
to do with a conversation going on in another forum I'm part of and thought
it might make an interesting addition to your thoughts.

I do not believe the homebrew spirit of Amateur Radio is dead. I do believe
that there has been somewhat of a shift in thinking. As much a part of any
ham radio station today I think software falls right in there with
antennas, tuners and transceivers.

What if, instead of buying a hardware kit, you could buy the components of
software. Maybe some brilliant programmers can put together the building
blocks of the next great logging or PSK-31 terminal program? These
entrepreneurial programmers put together "kits" that you and I could key in
to something free like Visual Studio or whatever the current Linux or Apple
environment is. Along with the keying in, the programmers are guiding us
through the software from maybe simple how-to-program to more complex how
to interface with a certain rig's API.

I like to think that today's keyboard is equivalent to yesterday's
soldering iron. Both are responsible for the start of a lot of creativity.

Just a thought.

*/ I put a Noctua NF-A9x14 PWM  pusher fan on the inlet this helped a 
bit,with a  typical over during a cw rag chew at 28 wpm delays the onset 
of high speed by a couple of minutes depending on the temp in the shack.

With the big fan on the back *off* my idle temp is 31c with *no* the 
helper fan, with the helper fan wired to the radio which runs when the 
radio is on the idle temp is 24 c it pushes the air from the top inlet 
through the unit and out the back. Noctua fans sit on soft silicone pads 
no vibration no sound just moves the air along through the amp.

Its to bad a replacement fan for the KPA500 from Noctua can't be found 
these are well engineered fans moving more air and quietly.

Jack,

It would seem that you have tackled the most obvious stuff.
I don't know whether you have a bad display or not, so I suggest you 
contact K3support to see if they might have seen a problem like that.

I have heard about prior problems with PA MODE turning off, but I don't 
recall what is to be done about it.  A fault in the KXPA100 can cause 
it, and the support folks may want a fault report from KXPA100 Utility.

I'd like to thank the person who opened an E-Mail attachment that should 
not have been opened.

The attachment contained a trojan horse -- malware that then harvested 
E-Mail addresses from their machine.

I know it was a list member, because my E-Mail address for this list is 
exclusively used for this list, and I'm now getting unwanted "spoofed" 
mail telling me about packages that are undeliverable, or that I need to 
appear in court.

Those E-Mails have attachments, allegedly containing the details of my 
offense or how to claim the package.

The E-Mail is very generic.  If you read it critically, there is nothing 
that says it is from a legitimate shipper, legitimate court -- just a 
slightly scary call to action.

It's another trojan horse.

It seems to me that after 3,000 years, we would have learned to keep the 
metaphorical horse outside our cities, but no, there are some who say 
"look at the pretty horse!" and we all suffer.

Thank you for your future consideration.  I'll go change my E-Mail

Is the fan in the KPA500 a 92mm fan?  Noctua makes a 92x92x25 mm fan...

If the kxpa100 power slide switch is OFF, the amp depends on periodic polls from the kx3 to keep it on.

Hi Jack,

I recently experienced something similar to your PX3 situation.  When you
said "cold", I immediately perked up.

During winter field day, I decided to take my PX3 with me.  Our club worked
outdoors in about -2C degree weather.  The trailer I was in had a couple of
portable space heaters.  It felt like they were pumping out one BTU each
:-).  By the time I had the station setup, the temp increased to about 9C,
maybe.  It was still cold and I had to wear a coat.  Anyway, I digress.

When I powered on the PX3, the display was dark.  Picked it up to hear the
click of the power on.  I heard a click.  Hmmmm.  I tried a couple of
times.  I disconnected all the inter-connect cables and still no display.
I was a bit cold and had just finished exerting a lot of energy with the
setup (antenna as well), that I just left it disconnected and put it away.
I was a bit dejected, but I had to focus on the task at hand, because WFD
was going to start in moments.  I should have left it turned on for a
little while to see if the display came back on after the internal
circuitry warmed up a bit.  But that never occurred to me because every
other display in my station came to life immediately.

After the PX3 had a chance to settle at home in the warmer climes of my
shack, I connected everything back up and lo and behold, the PX3 display
lit up.  I was quite relieved.  I wrote off the experience to the fact that
the PX3 didn't like the cold weather.  I don't either :-)

Anyway Jack, I am happy to be another voice when you go to Elecraft support
regarding the PX3 display not turning on when the unit is cold.  I don't
know the actual temperature that the PX3 doesn't like.  But I never had
this issue before.  I can turn on the PX3, when in the house, and it comes
on immediately after having sat for days in my basement shack.

Regards,
Brian

Message-ID: <CAD4CdTNVZCzP0qg7g1WRbOxTz25nZ-UcubjYdPH9TyVVrJYVtA@mail.gmail.com>

It's my opinion that there has been virtually nothing
"new" related to antennas since the 1930's.  Only
the names have been changed, as the high number
of recent posters have shown.

Some even have reached "cult" status. I have a small
history of giving antenna seminars at hamfests, and
usually start a talk with "How many of you are using
G5RV's"?  Usually, a large number of hands go up.

I make the observation that there seems to be a high
level of interest in 20M.  After a pregnant pause for
the puzzled looks, I then point out that the G5RV was
designed as a 20M -ONLY- antenna. I have the original
Varney article from the RSGB where this is plainly stated.
I have no idea where the transition to an "all band"
antenna came from.

I then ask why go to the trouble to build dipole fed
with a "magic" length of open wire that is then
connected to a "magic" length of coax without any
form of impedance transformation?  The "required"
length of coax is (usually) much longer than needed
and ends up coiled up somewhere, as in the case of
a local friend who coiled his excess at his feet. Why
not run the open wire directly to a tuner ... which
-WILL- be needed anyway ... via a balun? Viola!
One has a classic, easily used "all band" dipole.

The "Carolina Windom"?  The Windom has been with
us since the 30"s, and the "Carolina" is a marketing
ploy.

A recent poster gave a correct description of the "why"
of an end-fed zepp

Message-ID: <8f86e430-2961-62e3-e116-4662c95cdd28@sdellington.us>

I think what this thread is about is effective, very lightweight 
antennas for backpacking, SOTA, bicycle touring, etc.  These are 
antennas that, not including the support, weigh just a few ounces. 
Whether they could be made to work better with hundreds of long radials 
is completely irrelevant.

Without question, the EFHW minimizes resistive losses due to the high 
feedpoint impedance, and eliminates the need for a feedline. If you 
model a typical antenna of this sort, say a 66 foot wire with a single 
38 foot support, and move the feedpoint around, you will find very 
little difference in the far field.  End fed is within a fraction of a 
dB of center fed, and requires no feedline.  Even 38 feet of RG-174 
would weigh much more than a simple EFHW tuner, and the coax loss would 
be about 1 dB on 20.  Now, one could make some ladder line with some 
number 26 wire and spacers, but imagine trying to get that untangled 
every time you put up the antenna.  (Another consideration:  These 
antennas should be quick and easy to put up.)

As I said, if anyone knows how to make a better, lighter antenna, let me 
know!

An aside:  There are two major loss components when feeding any antenna 
near ground.  One is due to the resistance which appears in series with 
the feedpoint. (I'll call this the feedpoint loss.)  The extreme example 
is a short vertical fed against ground, where the effective resistance 
of the connection to ground is large compared to the feedpoint 
resistance.  Raising the feedpoint resistance will reduce this loss, the 
other extreme being the EFHW.  The other source of loss is the 
interaction of the electromagnetic field of the antenna with the ground 
within some fraction of a wavelength from the antenna.  Even a vertical 
EFHW, with very low feedpoint loss, needs lots of long radials to 
minimize this loss.  Ideally, you want to minimize both sources of 
loss.  If a big radial system isn't feasible, it still helps to minimize 
the feedpoint loss.

Let's not be hasty in our judgement...

To be fair, it would be trivial to write a small script to harvest any
string that looks like an email address that follows the form of
/\w\sat\s\w\.(com|net|org|tld)/ (that's a word followed by a space followed
by 'at' followed by space followed by a word followed by a period and a
tld).

Just saying... our email addresses are plastered all over, and the above
form of obfuscation is fairly easy to defeat.  And then, there's places
where it's not obfuscated in the least, such as

http://lists.contesting.com/_rtty/2015-01/msg00047.html

which contains your "exclusive" address in its entirety with no obfuscation.

Not trying to call you out here, I'm just pointing out that there's a
million ways for me to acquire an address (if I were up to nefarious
designs).

Hi Brian,

Well it is usually about 65F(~18C) in the shack this time of year unless 
I turn on the space heater. Not really "cold" per se. The PX3 will 
misbehave on start up or after having been turned off for about 5 min. 
even in warmer times. I guess what I mean by cold is different from 
Canadian cold... :)

Thanks for pointing that behavior out though... temperature may be an issue.

Do people still have problems with SPAM? I've noticed a significant drop in
the past year or so. Using Google GMail, they catch most of the spam before
I ever see it. I do check my spam folder at times just in case but boy oh
boy SPAM seems to have become a lot less of a problem lately.

In the case of the OP, he's using a disposable address. I think Lynn is
giving us a warning to be careful and not so much complaining he received
spam. I think?

I 100% agree... careful what you open. Also be aware, your email is already
known to anyone who cares to dig. No real covert technique required. For
that matter, so's your home address.

No increase in SPAM for me lately. 

As Kev notes, it has become more and more of a non-issue here even though my
e-mail address is all over the internet. 

Okay, now I'll probably get a bonus rush of the stuff because I said that!

Kevin, you are correct.  It's not the "spam" per-se, but the likelihood 
that people on this list are receiving trojan horses, and opening them.

I know this address appears in exactly one place: here.  It was 
harvested from this list in one way or another.

It's possible someone found and signed up just for the purpose of 
harvesting, but that takes time, and anyone who is harvesting is going 
to find the easiest way possible.

That's a trojan horse.

The E-Mail messages all look like this:

Dear Sir or Madam,

This is to inform you to appear in the Court on the February 16.
You are kindly asked to prepare and bring the documents relating to the case to Court on the specified date.

We attached the Notice to this e-mail.

With sincere thanks,
  ,
Court Secretary.

(attachment removed)

I'm not tempted to open the attachment, because it contains a script to 
harvest addresses and deliver that to someone who will use it to spam.

This is just one kind of trojan horse.  Others encrypt all your files, 
and offer to sell them back to you.  Some will try to steal your banking 
info.

Please just read anything with an attachment carefully.  Ask yourself 
"does this even look real?" before you open it (or click on a link).

" if the radio is on the ground, or near the ground, then the antenna is 
a vertical."
Wes  N7WS

Does this statement actually mean that  horizontally polarized antennas 
do not exist for those, whose radio is not high enough above the ground. :)

Not to rain on anyone?s parade, but I?d wager you would need at least several hundred, maybe thousands more serious buyers, for it to be financially viable for Elecraft (or a 3rd party) to make a panadapter for the K2.

BTW, is it not the case that the K2 is a traditional superhet?  That means you?d not have a ?free ride? that you would have with an SDR? I/Q signals already available.  Maybe the P3 would be adaptable for the K2..

I have a K2 half built on the Bench and a mcHF on my desk that I built last summer
I would love to see a multi-band BiTX (I have built a BiTX20A in the past as well).

I'm let to believe that there is a market out there for full kits so maybe I'm just not looking in the right places.

Message-ID: <SN1PR06MB22874EB0C0300BE3C491F4FAE7460@SN1PR06MB2287.namprd06.prod.outlook.com>

This is arguably OT, but I have just installed the N1MM+ logger and haven't yet had a chance to research where to access that user group.  So I've come here for help . . . 

Setting the program up for the ARRL DX Contest CW, when I try to enter made up QSOs just to try it out I get the error message "Missing/Invalid Power."  The Manual says that when that message appears, it means there is some element in the exchange that is either missing or invalid.  When starting the new log file I entered "medium" for power, and entered as the exchange only "CO" for Colorado.  Actually, CO was already populated.  The ARRL rules provide that DX stations should include their TX power in the exchange, but that W/VE stations do not.  My U.S. QTH in the configuration file is correct.  So I am confused - anyone know why I am getting this error message?

Tnx in advance,

Ted, KN1CBR

Ummm ... maybe not.  The email address of everyone who has recently 
posted to this list resides in the trash folder on my computer where it 
went after I read it, and where it will stay until a few thousand 
accumulate and I empty the trash. This is probably also the case for 
most everyone else.  My computer is pretty well protected behind several 
firewalls, but if someone got in, they're all there for the taking.

A lot of so-called "hacking" is pretty low-tech.  Hillary Clinton's 
campaign emails were taken because someone sent her campaign manager 
[John Podesta] an email requesting him to "update his password" and 
conveniently providing a link to do that, which he did, dutifully 
logging in to their server with his password.

Not at all -- but the fact is that running QRP into poor antennas is the 
equivalent of having both hands tied behind your back. If that pops your 
cork, great. FWIW, I've worked 165 with 5w in about four years. But I 
have great antennas.

Mr. Podesta is a good example of what I'm talking about: he was asked to 
update his password, he didn't look at the message carefully and ask 
himself if it was genuine.

There is nothing magical about Trojan horses.  They rely on someone 
trusting that the offer is genuine, and following the "call to action" 
when they really are not what they seem.

Thanks, Ryan.  That worked.  The Manual reads : ?. . . it does not believe your entered exchange is in the proper format for the contest.?  I had read the word your to mean my, but in fairness to the authors that?s more my error than theirs.  So to RTFM we could add RTFM-C!  (carefully!)

You must have the other op's call sign and exchange entered in order to log the contact. For W/VE stations, the exchange is RST and state or province; you need to enter the other op's state or province in the text field misleadingly labeled "Pwr."  This field is also where the abbreviation for output power goes for DX stations. The program will also accept in the log a W/VE station with a power exchange, even though this isn't really appropriate per the contest rules.

It is really unfortunate that advice like this continues to be...excuse the pun...propagated on forums such as this, when there is so much published information to the contrary freely available on the Internet and/or in books in your local library.

I have already quoted one source but I'll do it again for emphasis. (Hopefully, the formatting will survive)

  Devoldere in "Low-Band DXing", Chapter 9 says:

        4.3. The Radial System for a Half-Wave Vertical
        Here comes another surprise. A terrible misconception
        about voltage-fed verticals is that they do not require either a
        good ground or an extensive radial system.

        4.3.1. The Near Field
        If you measure the current going into the ground at the
        base of a ?/2 vertical, the current will be very low (theoretically
        zero). With ?/4 and shorter verticals, the current in the radials
        increases in value as you get closer to the base of the vertical.
        That?s why, for a given amount of radial wire, it is better to
        use many short radials than just a few long ones.
        With voltage-fed antennas, however, the earth current
        will increase as you move away from the vertical. Brown
        (Ref 7997) calculated that the highest current density exists
        at approximately 0.35 ? from the base of the voltage-fed
        ?/2 vertical. Therefore it is even more important to have a good
        radial system with a voltage-fed antenna such as the voltage-fed
        T or a ?/2 vertical. These verticals require longer radials
        to do their job efficiently compared to current-fed verticals.

Another invaluable source is Rudy Severns, http://www.antennasbyn6lf.com/ Rudy's work is meticulously measured, beautifully documented and presented.  He has written many articles for QEX, which are available on his site or via an Internet search.

This thread is a long one and frankly I didn't follow it at first, but a little 
research says that the OP was interested in bringing a coax feeder directly into 
the radio from the end of a wire.  He incorrectly called the coax a 
"counterpoise", instead of an extension of the wire which it really is, because 
it's going to radiate, but never mind that.  In this case, the antenna is a 
"sloper" whether it is called that or not.  If one end is higher than the TX 
then there is a vertical component to the geometry and the radio chassis is the 
"counterpoise." :-)

Not true, Ron. Most AM broadcast transmitting antennas are in the range 
of 80-90 electrical degrees (a quarter wave).  Nearly all of the Class I 
clear channel stations use antennas that are at least 180 electrical 
degrees. You can see this data for any US station at

https://www.fcc.gov/media/radio/am-query

WLW's tower is 189.3 degrees.  So is WLS.  WGN is 195 degrees. WBZ uses 
an array of four towers that are 188.5 degrees.  WIND on 560 kHz near 
Chicago, has an array of four 100 degree towers. The station where I 
worked in my home town has an array of four 82 degree towers.  And so on.

Hi Ted,

When I joined the current reflector several years ago, how to sign up 
was  prominently posted on the website where we download the software.

As a first guess -- look at the "Station Info" tab on the Config tab on 
the main menu line. Is all that info filled in correctly?

Clifton Web used to  make  a internal precision IF buffer to a SMA connector, 

And Tony made me a little surface mount K2 IF softrock,

which HDR and all those others works great as a basic K2 pan adaptor.

My K2 SN 40 (now K2-100) is all tricked out with everything that was ever available.

But since I have a K3s  with the full K-line,  K1, KX1,  KX2, KX3 with PX3 and KPA100,

My  K2/100 with XV50, is my six meter monitor.  So the basic pan adaptor works

excellent to see band openings.

The P3 will work with the K2, although you need to modify the K2 to get 
an IF output signal.  In the P3 menu, go to "Xcvr Sel" and select "4915 
kHz" or "4915 kHz (inverted)" depending on which band you're on.

The P3 display does not indicate the K2 frequency, receive bandwidth, 
etc. so it's not a full integration, but it does work.

The ARRL rules provide that DX stations should include their TX power in the exchange, but that W/VE stations do not.? My U.S. QTH in the configuration file is correct.? So I am confused - anyone know why I am getting this error message?

Ray,

If you provide the K2 with an IF output, the P3 will work just fine as a 
panadapter.  You need a buffer amplifier for the IF output.
LP-Pan will also work, but you need software running on the computer - 
NaP3 or Win4K3 should work nicely.

KFBK in Sacramento uses [or used, my info is a few years old] a 
center-fed half-wave vertical ["Franklin"] antenna, said to be the only 
one left.  It's ... interesting. [:-)  KFBK is also the originator of 
the first out-phasing BC TX which became the RCA Ampliphase [or 
Amplifuzz if you ever had to get one to pass PoP].  KFBK is also the 
radio birthplace of Rush, "Bloviator in Chief," although that's probably 
far less important than the Franklin.  There was a radial field under 
the Franklin, it may have rusted into oblivion by now, I'm not sure it 
was all that important, it's located in the flood plain north of 
Sacramento ... moderately wet, they grow rice in the area.

That's correct Jim. I meant close to 90 degrees (1/4 wavelength). Some of
the "big guns" do have 1/2 wave tall antennas, but most are near 1/4 wave
tall. 

Tnx for catching that.

Not true, Ron. Most AM broadcast transmitting antennas are in the range of
80-90 electrical degrees (a quarter wave).  Nearly all of the Class I clear
channel stations use antennas that are at least 180 electrical degrees. You
can see this data for any US station at

https://www.fcc.gov/media/radio/am-query

WLW's tower is 189.3 degrees.  So is WLS.  WGN is 195 degrees. WBZ uses an
array of four towers that are 188.5 degrees.  WIND on 560 kHz near Chicago,
has an array of four 100 degree towers. The station where I worked in my
home town has an array of four 82 degree towers.  And so on.

Yep, flamethrower of No. Cal.  The groundwave coverage is amazing.

Imagine how big that thing would be if they were on 580 instead of 1530  :^)

KFBK in Sacramento uses [or used, my info is a few years old] a
center-fed half-wave vertical ["Franklin"] antenna, said to be the only
one left. It's ... interesting. [:-) KFBK is also the originator of
the first out-phasing BC TX which became the RCA Ampliphase [or
Amplifuzz if you ever had to get one to pass PoP]. KFBK is also the
radio birthplace of Rush, "Bloviator in Chief," although that's probably
far less important than the Franklin. There was a radial field under
the Franklin, it may have rusted into oblivion by now, I'm not sure it
was all that important, it's located in the flood plain north of
Sacramento ... moderately wet, they grow rice in the area.

FWIW, I've had the 'UN-deliverable package' email, but Windows Defender 
warned me.  I recognized it as a phony about the same time.  Still, I 
was impressed with Defender.

I've been getting several phone calls from the Ransom-ware people, and I 
tell them they should be ashamed of themselves.  They hang up immediately.

 From the WWV site:

The WWV antennas are half-wave vertical antennas that radiate omnidirectional 
patterns. There are actually five antennas at the station site, one for each 
frequency. Each antenna is connected to a single transmitter using a rigid 
coaxial line, and the site is designed so that no two coaxial lines cross. Each 
antenna is mounted on a tower that is approximately one half-wavelength tall. 
The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 
MHz, is about 7.5 m tall. The top half of each antenna is a quarter-wavelength 
radiating element. The bottom half of each antenna consists of nine 
quarter-wavelength wires that connect to the center of the tower and slope 
downwards to the ground at a 45 degree angle. This sloping skirt functions as 
the lower half of the radiating system and also guys the antenna

As a side note, several years ago when my late wife and I were still traveling 
around in an RV we were near Ft. Collins.  As I have done with other stations I 
telephoned the site and asked whether I could get a tour.  The NIST guy was 
incredulous and said that no way did they give tours.  I said, pity, I'm an 
engineer and ham and am disappointed.  He thought for moment and then said, 
"Actually, we have a contractor doing some work here and the gate is unlocked.  
If you were to drive in and look around you wouldn't be bothered, but please 
stay in your car."  So we did.  The WWVB antenna was pretty impressive, but 
nothing like NAA in Cutler, Maine.

On the low bands most end fed half waves are inverted L's or fairly close
and for very good reason.  That's due to the kind of support people
commonly have for an 80 meter wire that's a total of 135 feet long.

Most commonly, a pair of trees, a horizontal wire between them, and at one
end of it connected to a wire dropping vertically to the ground plus some
kind of matching network at the ground or elevated counterpoise. The only
weight is the aerial wire itself, no heavy baluns or coax in the air to rob
the "L" of height.

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return in 1 week to keep this great thing going and growing.

Today was a good day as I worked 2 stations from my qth in Manitou Springs, CO.
I am running a K3 at 5 watts into an end fed half wave up about 30 feet.

I worked:
N5GW          GENE in Vicksburg, MS
W5RES	     LARRY in Haileyville, OK

Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

Message-ID: <CADa2mvhVCuFMDEhmZhZtDySQ3KkCcWhAMqx63En-Me+pGnTTCw@mail.gmail.com>

I can vouch for the EFHW.  It works great.  I built a parallel tuned
circuit using a roller inductor and a 15-350pf cap.  I have used this
several times on 20 meters feeding a 33.5 foot vertical wire.  I use about
4 10 foot radials, which is probably overkill, and run it through a good
choke and it has been a great performer.  I have also used this box to feed
a 20 and 40 meter halfsquare.  I have ran 500 watts through both the half
square and the 20 meter EFHW with no arcing and an SWR  < 1.5 and a
reactance of 3 or 4.  No problems, works great.

The only issue I have had is that the EFHW tends to be a little bit noisier
than a traditional vertical, but I can put this antenna up and operate in
less than 10 minutes so it's worth the small amount of extra noise.

Hi to all:

I apologize for the late response. I am using a K3S and Heil PR10 here and had the same problem as was noted in the original post. I have found that the PR10 will only work correctly using the HP input in the Mic settings. I use a mic gain setting of 12. I posted a note on this problem a while back and Don provided the correct response and my setup has worked FB ever since, and have been getting excellent audio reports on the air, which is the real test of the settings. I?ve had a number of exchanges with Heil re their recommendation of the LH setting for the PR10 and never was able to change their mind or resolve the issue. Just my two cents for what it?s worth.

Anybody got any idea about using a ?? of light weight 300? twin lead
feed line to a ?? vertical wire?

This might alleviate the HI Z feedpoint and effectively make an end fed
(bent) ? ? Zepp.

So, for 20 Meters, roughly 16 feet of 300? connected through a 4:1 balun
at the radio, and  33? feet at the other end up in a tree or pole.

The down side is that it would be a single band antenna and maybe a tad
cumbersome for 40 M, requiring about 33 feet of twin-lead strung out but
probably NOT laid on the ground.
There IS such a thing as shielded twin-lead that might be OK on the ground,
but it'd be too much extra weight for a portable set-up.

I can vouch for the EFHW.  It works great.  I built a parallel tuned
circuit using a roller inductor and a 15-350pf cap.  I have used this
several times on 20 meters feeding a 33.5 foot vertical wire.  I use about
4 10 foot radials, which is probably overkill, and run it through a good
choke and it has been a great performer.  I have also used this box to feed
a 20 and 40 meter halfsquare.  I have ran 500 watts through both the half
square and the 20 meter EFHW with no arcing and an SWR  < 1.5 and a
reactance of 3 or 4.  No problems, works great.

The only issue I have had is that the EFHW tends to be a little bit noisier
than a traditional vertical, but I can put this antenna up and operate in
less than 10 minutes so it's worth the small amount of extra noise.

The point and click function of the P3 is really a misnomer. It is more on the order of twist and push. When operating a contest in S&P mode and using the P3 to search for signals, I find the current functionality suboptimal. I have yet SVGA option with a large screen; it would be so much easier to be able to use a mouse and have true "point and click". I wonder if this will ever be a reality. It would make the P3 far more functional.

Mike,

Hook up you want for the K3, KPA500 and KAT500 is
shown in the KAT500 manual.

The P3 manual shows the K3 to P3 connection.

If you don't have the manuals, ALL of them are
available for download at the Elecraft site.

Hi Ed, 


Try operating your P3 in fixed spectrum - tuned VFO mode (FixMode). 
You simply turn the K3 dial to "point" the VFO Cursor to the signal 
of interest displayed on the P3. 


Its very fast, faster than point and click with a mouse

Frank,

You are drinking the cool aide. With the mouse click option you can tune all over the band quickly, sampling all kinds of signals in the time it takes to retune one new station. I complain about this at Dayton every year and am always told it?s not necessary. It?s not necessary any more than the P-3 is necessary but it sure would be a nice feature.

Hi Wes, 


The WWV half wave vertical is much like the "Happy Accident 
Ground Plane" described in January 1957 QST that uses only four 
sloping radials, sloped downward 30 degrees to produce direct 
50 ohm feed point impedance. The sloped radials make them into 
radiators, hence the feed point impedance is raised to 50 ohms with 
the appropriate slope. 



The feed points of the WWV antennas are 1/4 wavelength high, but 
I'm sure the performance would be little affected by lowering it 
somewhat. 


This antenna isn't quite a balanced half wave vertical, it isn't quite 
a ground plane, and it isn't quite a sleeve dipole but it definitely 
works very, very well. 


I used a 20 meter "Happy Accident Ground Plane" mounted 50 feet 

up in a maple tree for many years when I was in Rhode Island during 
the 1960s and worked the world with it.

>From the WWV site: 

The WWV antennas are half-wave vertical antennas that radiate omnidirectional 
patterns. There are actually five antennas at the station site, one for each 
frequency. Each antenna is connected to a single transmitter using a rigid 
coaxial line, and the site is designed so that no two coaxial lines cross. Each 
antenna is mounted on a tower that is approximately one half-wavelength tall. 
The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 
MHz, is about 7.5 m tall. The top half of each antenna is a quarter-wavelength 
radiating element. The bottom half of each antenna consists of nine 
quarter-wavelength wires that connect to the center of the tower and slope 
downwards to the ground at a 45 degree angle. This sloping skirt functions as 
the lower half of the radiating system and also guys the antenna 

As a side note, several years ago when my late wife and I were still traveling 
around in an RV we were near Ft. Collins. As I have done with other stations I 
telephoned the site and asked whether I could get a tour. The NIST guy was 
incredulous and said that no way did they give tours. I said, pity, I'm an 
engineer and ham and am disappointed. He thought for moment and then said, 
"Actually, we have a contractor doing some work here and the gate is unlocked. 
If you were to drive in and look around you wouldn't be bothered, but please 
stay in your car." So we did. The WWVB antenna was pretty impressive, but 
nothing like NAA in Cutler, Maine.

Constructing my old K2 was one of the most fun and challenging things I have done with electronics.  Before that I built a few things long ago with Heathkit.

Top end modern transceiver technology has moved beyond the K2, which is why Elecraft did a complete redesign with the K3 and K3s.   The K2 is a nice rig, but the K3s is so much more.

Modern electronics is all about miniaturization.  Nearly all the components are smaller, they have to be installed at the surface instead of via through-board solder holes.   The result is that you can now create transceivers that have top notch performance yet fit in the palm of your hand.  Witness the K3s and K2s.

To work with miniaturized surface mount components you need specialized equipment and specialized skills.  A simple $100 soldering station and some rework tools is no longer good enough for this kind of work.  There are relatively few amateurs who could or would tackle a kit where the great majority of the components are tiny and surface mounted.

I imagine Elecraft could re-engineer the K3 with non-surface mount parts.  I imagine the box will have to be a lot bigger.  Same performance?  Perhaps, perhaps not.  That will be a significantly different beast.

I think the added cost of re-engineering would probably make the kit prohibitive.

There are still kits around, and smaller projects are still reasonable using traditional construction methods and parts.  However, the era of solder-your-own kits is definitely in decline.

Or we could all lease some equipment and learn how to surface mount.

Mike,

It does not include the P3, but there is a diagram for the rest on page 
5 of the KAT500 Owner's Manual.
Connect the P3 and K3 as shown in the P3 manual, These connections are 
independent of the rest of the K-line connections.

73,

I have used both.  I much prefer the P3.

The LP-Pan is tricky to set up and configure, and computers can be balky and unreliable.  Adjustments can be tricky and counterintuitive, and require specialized knowledge of how the particular program works.

The P3 is a plug and play device.  Adjustment is via various labeled tuning knobs and becomes pretty easy with a little practice.

In fixed mode the P3 can easily and directly tune to an interesting point on the band.  Just rotate the knob to bring the cursor into position and press the button.  Just as fast as a mouse.

Hi Jimmy, 


I agree, point and click is a desirable feature, and shouldn't be 
difficult to implement via a mouse connected to the P3 USB port. 



Since your option doesn't exist (at least not yet), suggest you try 
my method which actually exists and works very well

Frank, 

You are drinking the cool aide. With the mouse click option you can tune all over the band quickly, sampling all kinds of signals in the time it takes to retune one new station. I complain about this at Dayton every year and am always told it?s not necessary. It?s not necessary any more than the P-3 is necessary but it sure would be a nice feature.

I also wanted to thank Frank for a great suggestion.He hit it right on the nose. I always forget about the usefulness of an RF ammeter. When I was a kid in the ?60?s hanging around the OT?s a couple of them used these in the open wire lines to tune for maximum current. No concern of SWR as that wasn?t important with pi and linked outputs in your tube rigs! Now I just have to figure out a way to do this in the field?I still have some wonderful Weston meters one of the guys gave me lo those many years ago.

Thanks Don. I finally figured that out. I also found a spare KPAK3AUX cable (I have no idea) in the shack. I'm up and running. 

73,

Mike AD5A 

Just a side note, I thought I ordered the KAT500-F, but I guess I ordered the kit. I brought the unopened box with me to a second QTH in Santa Fe, NM, where I was going to plug and play. Well I opened the box and realized that I had some work to do. I finished late and then tried to connect everything. My brain wasn't in high gear and reconciling the two diagrams just wasn't in the cards. After some coffee this morning and reviewing the drawings again, it made some sense. Then the fortuitous discovery of the needed cable, all is well.

Hi,
I was just operating on 15 cw working west Africa no problem, changed bands and all of a sudden no audio and no power out! RX ant is not engaged. Does anyone have any suggestions?

The radio has been fine last night and 20 minutes ago and again to restate, it has no audio and no power out even into a dummy load

Any help would be appreciated

thanks

Paul Saffren (N6HZ) can help us understand why we still haven't seen
Mouse-n-Click QSY support for the P3 and PX3.

If you use a 2.4 GHz wireless dongle which supports both a keyboard and a
mouse, the HID report sent to the P3 / PX3 contains not only the keyboard
information,

        struct KBDINFO {
                struct {
                        uint8_t bmLeftCtrl : 1;
                        uint8_t bmLeftShift : 1;
                        uint8_t bmLeftAlt : 1;
                        uint8_t bmLeftGUI : 1;
                        uint8_t bmRightCtrl : 1;
                        uint8_t bmRightShift : 1;
                        uint8_t bmRightAlt : 1;
                        uint8_t bmRightGUI : 1;
                };
                uint8_t bReserved;
                uint8_t Keys[6];
        };

but also the mouse information,

        struct MOUSEINFO {
                struct {
                        uint8_t bmLeftButton : 1;
                        uint8_t bmRightButton : 1;
                        uint8_t bmMiddleButton : 1;
                        uint8_t bmDummy : 5;
                };
                int8_t dX;
                int8_t dY;
        };

Obviously, the P3 / PX3 is ignoring the mouse information.

Basic Mouse-n-Click QSY functionality would require ~25 lines of firmware.

ANY switching power supply is a potential noise source, and even the 
best can be heard in antennas that are close enough to it. The one 
Elecraft sells is pretty quiet, but I heard it in a 160M vertical that's 
25 ft from it.

Well, the KFBK Franklin is two vertical 180 deg co-linear elements 
center fed [in-phase, I think], so I guess it would be about 1,600 ft 
[almost 500 m].  A couple of the TV towers in Walnut Grove down in the 
Delta are 2,000 ft [600 m], but they're not center fed. [:-)  I think 
most "half-wave" BC verticals are close to but not exactly 180 deg.  
IIRC, KFI [640 KHz] in Los Angeles has a 725 ft tower which is almost 
exactly 180 deg  but has a capacity hat that extends it to an effective 
195 deg or so. When you drive by it on I-5, it is one very tall tower.

In the 1960's, you could work the world with 20 watts to a window 
screen.  Peak of Cycle 19 was in the front half of the 60's. [:-)

Well, here I am packing my bags for a trip to VP2M.  I think I will 
leave my RM35 home and take along the power werk switcher. I'll tolerate 
the few birdies I hear from the switcher for the difference in 
size/weight.  The answer to the question really depends on your situation.

Ken,

Sorry to be the bearer of bad news, but G4HUP died last week at the age of 68, a great loss to the community.

We have no word on the future, if any, of his excellent products.

Hi Fred, 


When I started DXing in about 1962, Solar Cycle 19 was quite weak 
and reached its minimum in 1964, the year I made the #1 USA low 
power score in the ARRL CW DX Contest using my 20 meter Happy

Why would you change out an Astron RS35M?  Unless you need to
make the K3 station portable where the weight and size of the
Astron is an issue, the RS35M will be both much more quiet and
much more reliable than any switcher.

Even if the Astron is getting a little unreliable, an overhaul
(replacing the diodes, pass transistors and possibly filter cap)
is likely to be more cost effective than purchasing a switcher.

For repair/overhaul information see: 
<http://www.repeater-builder.com/astron/astron-repair/astron-repair.html>

or for a more in-depth modification/overhaul that replaces the 723
regulator see: <http://www.bwcelectronics.com/articles/WP20A190.pdf>

I have been using that Powerwerx power supply since before Elecraft started listing them on their web page and it is a good, quiet power supply. I use a big linear power supply at home and the Powerwerx unit for portable operations since it is a good compact supply. I got one for my newly licensed YL and it is on all the time with her rig with no issues and no noise.

Ameritron does not make a band switching cable for this combination.  Does
anyone have information for me to make or modify a cable?  The combination
works great but I sure miss the automatic amplifier band switching.  I have
the KX3 and the KXPA100 (using the KXPA100 utility command tester) both set
at 9600 baud because the ALS-1306 only accepts 9600 baud but I don?t
understand serial cables very well and the ALS-1306 does not use a standard
straight through cable or a null modem cable either.  It uses custom
proprietary cables for different radios.

N1MM is saying you have not entered the DX station's power into the QSO entry window.  So when trying test qsos, type the the dx station call, hit space, then enter a power and hit enter to send your report or log it, depending on whether you are S&P or running.

Also, after entering stuff into the log, if you type WIPELOG in the call sign entry field, N1MM+ will clean the log.  Although somehow we have had problems with that in a sequence number contest like SS where the sequence number doesn't get cleared and you start the contest with a number other than 001.  Haven't sorted that one out yet.

Cheers,

Fred KE7X

Subject: [Elecraft] Question about N1MM+ Logger

This is arguably OT, but I have just installed the N1MM+ logger and haven't yet had a chance to research where to access that user group.  So I've come here for help . . .

Setting the program up for the ARRL DX Contest CW, when I try to enter made up QSOs just to try it out I get the error message "Missing/Invalid Power."  The Manual says that when that message appears, it means there is some element in the exchange that is either missing or invalid.  When starting the new log file I entered "medium" for power, and entered as the exchange only "CO" for Colorado.  Actually, CO was already populated.  The ARRL rules provide that DX stations should include their TX power in the exchange, but that W/VE stations do not.  My U.S. QTH in the configuration file is correct.  So I am confused - anyone know why I am getting this error message?

Tnx in advance,

Ted, KN1CBR

Looking at the specs, the K3s could draw up to 25 amps max, the KAT500 could draw up to 1 amp max and the Powerwerx supply is rated at 25 amps continuous duty. Sooooo .... It "may" be ok. That would depend on how long you hold the key down or transmit rtty. 

You can get the Powerwerx unit that contains the built in volt/amp meter or purchase the external meter unit and see what the actual current draw is on transmit.
I don't have a KAT500 so maybe someone else here has tried that combination with that power supply. I have had no issues with my K3 or FT857D or IC7200 and the LDG 200pro antenna tuner.

I agree fully with ED.  I had thought the ability to plug a mouse into the

added soon for us that want to use a mouse for point and click.  73s Jim

The point and click function of the P3 is really a misnomer. It is more on 
the order of twist and push. When operating a contest in S&P mode and using 
the P3 to search for signals, I find the current functionality suboptimal. I 
have yet SVGA option with a large screen; it would be so much easier to be 
able to use a mouse and have true "point and click". I wonder if this will 
ever be a reality. It would make the P3 far more functional.

The K3/K3S draws peak current on transmit, and is generally greatest on 
the higher bands (especially 6M) where efficiency of the output stage is 
lower. The KAT500 draws max current when tuning. The rest of the time it 
draws very little current. In general, any PSU that will run the radio 
will also run low power accessories like the P3 and KAT500.

I normally tune using the P3/SVGA monitor for tuning. For me, it 
is a visual experience. During the WPX RTTY contest last 
weekend, I set my span to about 25, so I could see both tracks 
of the RTTY signal. I could get close enough to decode using the 
KPOD knob. I fine tuned by ear, and by using the Crossed Ellipse 
Indicator/XY scope in cocoaModem. I use a similar technique to 
tune CW and can get the APF tuned by lining up the tuning 
indicator with the signal in the waterfall.

The bigest issue with this technique is the lag between turning 
the knob and seeing the SVGA display change. Using a mouse would 
make the lag less important. Where I would a mouse almost all 
the time is in the big jumps. On a single band contest, I start 
at one end of the active area of the band and S&P my way to the 
other end. By then, the band conditions have changed enough that 
is is worth going through again, so there is a big jump to the 
other side of the active area. There are also sometimes gaps big 
enough to be too slow with knob turning.

There may be a technical implementation problem for Elecraft. 
The last time I paid attention, the P3 didn't support USB hubs. 
They would need hub support to use both a mouse and keyboard at 
the same time.

tl:dr I like to build things. Getting all the components 
assembled in a kit is a wonderful step forward toward the fun part.


I have built several kits with SMD components using just a 
temperature controlled soldering station. I think I could get by 
with a cheap Radio Shack soldering iron, but I certainly don't 
want to. (I like automatic spark advance in my car as well.)

The basic approach is to tin the pads on the board with solder 
and clean things up so there are no bridges. Solder one 
end/corner of the device and adjust it so it lines up with all 
pads. Then go and solder the rest of the pads. This technique 
works well with 8 pin devices. I would be in unknown territory 
soldering a 400 pin grid array device. :-)

I bought a hot air rework device from SparkFun 
<https://www.sparkfun.com/products/10706> for $115 which I use 
when I have to remove a SMD component. The video on the page is 
a good introduction to removing SMD components.

I will note in passing that the mantle of electronic 
construction has moved from the ham community to the builder 
community. Their suppliers are now the best place to learn how 
to deal with modern electronic components.

only be true for small frequency changes. 

The last time I asked Elecraft about this feature, I put this to the
test by comparing the two VFO knobs on the K3 against the small knob on
the P3-SVGA, and comparing both of those against an SDR panadapter that
was linked to the K3 and tuned with a mouse. 

The time taken to tune with a knob increases with the frequency span of
the display, and with a wide display this can take several seconds of
vigorous spinning. Changing into 'high gear' using the RATE button
doesn't really help because the button-presses bring a time penalty of
their own, plus a significant risk of stabbing the wrong button.

The unweighted VFO B knob is also significantly slower than VFO A.

But if the mouse is close to hand, the time taken to point and click
anywhere on the panadapter screen is *completely independent* of the
on-screen frequency span and is never greater than 2-3 seconds. My mouse
sits right between the keyer paddles and the K3 tuning knob so it's
always easy to find, and then the hand goes naturally back to the VFO
knob for the final zeroing-in. 

Meanwhile, the cursor knob on the P3 came in a hopeless third. For
anyone who needs to QSY quickly, this is not a serious operating
feature.

So there really is no contest here. For QSYing rapidly across a wide
frequency range to jump on new stations, the mouse is a very clear
winner.

And that, I regret to say, is why my second K3 purchase did not include
another P3. Without the mouse feature I wouldn't even consider it.

This assumes the keyboard and mouse have separate / dedicated 2.4 GHz
wireless dongles.  There are plenty of keyboard / mouse combos which share
the same wireless dongle.  I've tested several of them with my PX3.  Of
course, the PX3 ignores the mouse HID report at the moment, however, the
keyboard HID report is interpreted just fine.

USB hub support is certainly preferred, allowing users more flexibility in
selecting their keyboard and mouse.  As we've noted in the past, USB hub
support would allow a thumb drive to be connected with the keyboard and
mouse.  For example, a unique key combination could be used to capture the
P3 / PX3 screen to the thumb drive.  The P3 / PX3 currently supports the
ability to capture the screen, however, you first must remove the keyboard
dongle and insert the thumb drive.

I suspect many (most?) users would be content with only Mouse-n-Click QSY
(no keyboard).  This wouldn't require USB hub support.

I've found that surface mount is not that hard just different.
Probably the same as when electronics switched from Tubes with point to point and big irons to PC boards with IC's and and smaller irons.
In a lot of ways surface mount is easier, (no leads to bend, reshape and trim)

I do have to agree It does seem that other hobbies are taking the lead in going to surface mount.

 Subject: Re: [Elecraft] Full kits,
   
tl:dr I like to build things. Getting all the components 
assembled in a kit is a wonderful step forward toward the fun part.


I have built several kits with SMD components using just a 
temperature controlled soldering station. I think I could get by 
with a cheap Radio Shack soldering iron, but I certainly don't 
want to. (I like automatic spark advance in my car as well.)

The basic approach is to tin the pads on the board with solder 
and clean things up so there are no bridges. Solder one 
end/corner of the device and adjust it so it lines up with all 
pads. Then go and solder the rest of the pads. This technique 
works well with 8 pin devices. I would be in unknown territory 
soldering a 400 pin grid array device. :-)

I bought a hot air rework device from SparkFun 
<https://www.sparkfun.com/products/10706> for $115 which I use 
when I have to remove a SMD component. The video on the page is 
a good introduction to removing SMD components.

I will note in passing that the mantle of electronic 
construction has moved from the ham community to the builder 
community. Their suppliers are now the best place to learn how 
to deal with modern electronic components.

I will also testify that this antenna has worked well for us. My son above,
NS0R, has used it in favor of a beam because of a tower HOA issue with his
wife. LOL. Both of us have literally worked thousands of QSO with this
antenna. The Parallel tuner will handle most any HIGH impedance antenna,
that being 2000-5000 ohms. Having a roller inductor in parallel with a
variable cap really makes the difference. Once the dip is attained, the
bandwidth is the whole band on 20, and 15 both phone and CW will be under
2:1 or better. The hard part is getting the stray capacitance in the
construction out of the box. At times that has been problematic, but still
workable.

Clifton Labs products were acquired by DX Engineering:

Further to this.  At the time I wrote the previous message my K3S/100F was back 
at the factory again. On a previous visit Elecraft had installed the resistor 
need to power the K-Pod through the RJ12 connection.  So I was using my old K3 
without the mod and powering the K-Pod from an external power supply.  Couple 
that with the extension cable and I was reluctant to insist that the K-pod was 
really the culprit in the "dropped message" problem.

But since the radio has returned, I've used the K-Pod with the factory-supplied 
cable and I still get instances of a button tap activating a message, as 
displayed on the radio, but no message is actually sent.  BTW, this is with the 
TX disabled, so I don't want to hear the all too frequent, "You have RF in the 
shack and need a common-mode choke" answer.

Unfortunately, I have to keep this paperweight connected to the radio since when 
my fiancee asked what I wanted for Christmas, I said, "a K-Pod" and she bought 
it for me.

If Elecraft wants me to change my opinion on this they will make it possible to 
store the macros IN THE K-POD and play them out instead of the convoluted way 
it's done now.  IMHO of course.

1) Let's get it straight that the connector is RJ12, not RJ45. I've already
posted on using an adapter to extend the Elecraft-supplied cable from the radio
to the K-Pod.

2) I have Macro 13 (tap F5) set to activate MSG 1 (SWT 21)  As I've written
before, many times, tapping this button resulted in "MSG1" displayed on the
radio but no message was transmitted.

Same sort of experience here.  In 1957 if my DX-20 could load it, I transmitted with it.  I didn?t know any better. I should say, however, that when I lived in R.I. during the peak years of Cycle 19 and in New Haven during the peak years of Cycle 21, having the ocean as a neighbor didn?t hurt either.  Certainly better than the thick layer of decomposed granite my shack sits on now.

1530KHz is about 200m wavelength so 2 half waves in phase would be about
200m tall, approx 650'

It is with the latest beta firmware... 5.56, I have tested it with an rrc box at the control end and it worked great for tuning, I didn't test the macro buttons however.

Look at the release notes on the 5.56 firmware. Mg

entailed/what the modification does and how it might help!

Message-ID: <CALuSmOcTZq3VsPUkw5q2L-DBdsCCOVGyb-e6vcxEB9iZdmtvZQ@mail.gmail.com>

What is this "mouse" think you speak of?  I've moved on to using NAP3 or
HRD with the touch screen :)  It works really well on DigitalMaster with
the digital modes:  Touch the waterfall, start typing.

Actually, that's not entirely true...there are  just some navigation
elements that do work better with a mouse.  But not having point and click
with mouse is one of the reasons why I never did the P3, either.

Subject: [Elecraft] (OT) Follow-up on CW Resonant Speaker
Message-ID: <6aff2d3f.42e61.15a3a1830d6.Webtop.51@optonline.net>

Folks, I posted about having built the CW Resonant Speaker in the 
February 2017 and having problems with low audio. ?This is a follow-up 
report for those with interest in this subject.

It works! ?It's fabulous! ?It's unbelievable how great it sounds! CW 
pops out and background noise is significantly reduced.


I built it EXACTLY as described in the article and ordered the EXACT 
parts listed. ?My problem was not enough audio coming from either my KX1 
or my KX2 headphone jacks. ?


I purchased a fully assembled 15 watt mono amplifier -?Qianson TDA2030A 
15W Mono Channel Audio Power Amplifier Board AC/DC 12V AMP Module - 
Amazon for $11.80.


With the new amp, my speaker is acoustically resonant at 760 Hz and I 
have plenty of volume; enough to fill the room. ?The author had claimed 
"around 700 Hz" so it's in the ballpark. ?I can verify that the 
construction article was accurate.


I wanted 600 Hz so I built a vinyl sleeve to insert into the street 
elbow and set my sidetone pitch for 600 Hz then slid the sleeve up and 
down until I got a very obvious peak in volume.


I'm still a "can fan" for serious CW operating, but it's nice to be able 
to listen to sweet CW that pops right out now that the higher frequency 
sounds are substantially subdued.


This was a really worthwhile little project.

Noiseblocker does too (92x92x25), which I prefer due to color. :) I have no
idea if this is the correct size for the KPA500, I don't have one, and
can't vouch for doing the mod. BlackSilentPro would be the model I've used
in past fan replacements on switches and such. Disclaimer, I have no idea
how this will influence the thermal control of your KPA500. YMMY/mod at
your own risk. Perhaps a call to Elecraft to discuss?

Hi David, 

I'd prefer to have folks that are experiencing this problem email me
directly.  That way I can determine the best resolution path. The fix
involves replacing a surface mount capacitor which is located under the
power supply board on the front panel board. 

Kindly, 

Paul

The Cliffton Webb unit was specifically made for K2 exact signal/clean easy 
physical fit internally,
and a external  IF pass band filter for a clean signal no matter what kind 
of signals
are present in your shack.
Not a area of your receiver where you want to be hacking about. Just saying.

The Clifton Labs Z10000B was a general purpose instrumentation 
amplifier.  One version was specific for the K2 by adding a filter
The buffer amp at QRP projects is specifically designed for the K2.

Folks, I just returned from 5 days on the road for the Orlando Hamcation hamfest and saw this huge thread. As per list guidelines, please self moderate (i.e. - End) OT threads like this after 5-10 posts. Please do not wait for me to jump in.

Lets end the thread at this time - this topic has certainly been beaten to death.. ;-)

I stumbled across a K2 for sale on Ebay that I thought was rather 
"interesting".  It's one of those situations where you have no idea what you 
are really getting!

The K2 is actually described as a "CB radio"!  Wow!  Makes you wonder. 
Also, it is later described as a "K2/100", but that has to be wrong since it 
has no heat sink!  At least they do say "As IS for parts/repair".

Now, there probably is some value here, and maybe some good value, but how 
can you possibly tell?  Right now the bidding is up to $280, with a couple 
of days to go.  I'm just curious how much this thing will sell for.  If 
anyone else is curious, it is item # 162388838126.

I saw it but if you look close it appears that it was not built well
Long leads on caps and transistors, sloppy winding on toroids etc.

If you want to see spectrum on either side of the signal, you do not want a filter in the loop. Ideally, you would see the entire spectrum *before* any I.F. filtering on the panadapter.

The Cliffton Webb unit was specifically made for K2 exact signal/clean easy physical fit internally, and a external  IF pass band filter for a clean signal no matter what kind of signals are present in your shack.
Not a area of your receiver where you want to be hacking about. Just saying.

I am using it and it works PERFECTLY  on both sides of the signal.
If you want more explanation than I am prepared to provide,
Cliffs site info is still there, just not the products.

Hi Ron,

             The filter was a 200kc wide bandpass filter so you would see all 
the signals of interest.  So may have helped with the input to the LP Pan which 
was the hot setup back then.

	behavior

Okay, lets take Eric's lead and open an interesting thread directly 
related to an excellent Elecraft product. 



For years many of us have suffered with the odd behavior of the K3 
in CW PTT mode. There are at least two inexplicble aspects of K3 
CW PTT behavior that have forced many of us to use external 
Winkeyers rather than the poorly designed internal K3 keyer logic 
when the K3 is in CW PTT mode. 


For CW contesters, its necessary to operate the K3 in PTT mode 
to avoid unwanted VOX delay. But for some strange reason the 
K3 always applies VOX delay after external PTT is unasserted. 
I can think of no logical reason why VOX delay should be applied 
at the end of the external PTT input when the K3 is PTT mode or 
any other mode. When PTT is unasserted, the K3 should always 
immediately return to receive mode, no exceptions. 


When using the internal K3 keyer when in PTT mode, for some 
inexplicable reason the K3 behaves like its in QSK mode. The 
only way to avoid this is to use VOX rather than PTT mode or 
to use a foot switch when in PTT mode. Both alternatives 
are unacceptable. 


The band aid solution many contesters use with excellent results 
is to avoid using the internal K3 keyer and to use an external 
K1EL Winkeyer that generates both a key output and a PTT 
signal generated according to well designed Winkeyer CW PTT 
logic. 


Why can't the K3 implement logic similar to the Winkeyer to 
generate the equivalent of "Winkeyer PTT" when using the K3 
internal keyer when the K3 is in PTT mode?

There is absolutely nothing wrong or bad about the 723 regulator.  But
there are a lot of badly designed units using that IC out there.  The
designers did not read (let alone fully understand) the data sheet.  And
then not helped by the physical layout people, who don't appreciate the
effect "inappropriate" wire routing can have on a regulator with a high
loop gain. Don't blame the device for poor product design.

What does go bad over time with most "Ham market" linear PSU's, is not
so much the main cap (often too high a value) diodes or pass transistors
(unless this next issue has happened.)

High value reservoir caps can overly stress the rectifier diodes, and
transformer.   Ripple is to be expected across that, and is what the
regulator is there to remove...

Anyway.  The thermal interface between the pass transistors and heat
sink often deteriorates, not helped by the usual sloppy build quality in
the first place.  (I've even seen pop-rivets used to mount regulator
pass transistors!  BAD BAD BAD!)

Same for the main bridge rectifier if that is heat-sink mounted as
well.    If it is not, consider moving it to the heatsink, or fitting
one to it if there is room.

The cooler you can keep a semiconductor (within reason) the longer it
will last.   Wide variations of temperature are also bad, often for
where the leads are connected to a PCB, if not using flexible wire
resulting in failed solder joints.   Always "kink" the lead with a z
formation for mechanical stress relief, it'll last much longer as a result.

Power transistors with sockets too, can suffer intermittent lead
connections over time, due to thermal cycling and the minute repeated
relative movement between lead and socket, usually damaging the plating
on the semiconductor lead, resulting in bad connections.   Replacing the
socket will not cure that.

Dismantle, clean and re-apply fresh compound or thermal interface pad. 
Use fresh insulating (clamp) washers too if needed.   Most of all, do
not over-tighten those device mounting screws.   No, I can't quote a
torque, you'll have to research the matter, and consult the device
makers data sheet, if you can identify the devices that is...

Re solder any joints that appear a little suspicious around the high
power devices.   Replace any suspect socket connections by removing them
and soldering the wires to the device leg?s directly.  (If the device
legs plating is not badly corroded, if so, replace the device too.)

The same holds true for the pass transistor (and their drivers) emitter
ballast resistors.  Check their condition and connections.

No emitter ballast resistors?   Bad design...

For a any linear PSU, even a small fan wafting air over the heat-sink
will make a world of difference too, resulting in a much cooler PSU that
is much more reliable as a result.   If you don?t like the continuous
sound of that, fit a thermal switch to the heat-sink, say 50'C, to turn
the fan on when it gets hot...   (Or based on PSU output current...)

It works perfectly with HSDR that I use and several others, I have never 
used it with LP Pan however.

Hi Ron,

             The filter was a 200kc wide bandpass filter so you would see 
all
the signals of interest.  So may have helped with the input to the LP Pan 
which
was the hot setup back then.

May be Elecraft can also look at the 8 msec PTT delay which cannot be 
made longer without distorting CW. Some of the apmplifiers are not that 
quick.

If Wayne will be tearing up the code in this area, it might not be hard 
to fix the problem that the internal keyer weighting is much heavier in 
PTT mode than in QSK or semi-QSK VOX.

Frank,
Pardon my ignorance on this issue if the below is off target.
The asynchronous nature of an external ptt appears to be a problem. 
Suppose the K3 is in the middle of a long 100 watt dash and the external ptt signal is dropped.  It clearly takes some time for the RF tail to drop to zero.  One would seem to need to add some delay time for this to happen.  To avoid clicks one wants a shaped tail.  I dont see how the K3 can immediately go to RX.  
How fast a turn off and go to RX action do you want?  Is the normal 5 ms tail fast enough?

Of course if Winkey logic is programmed within the K3 the asynchronous problem goes away. 

The adjustable TXDELAY issue where the CW gets QSD with a setting more than 8 ms is an issue that has existed from day one.  People started complaining about it on day 2.  Elecraft has know about it for a long, long time. From what I am able to glean about the problem is that it may be really difficult to fix.  Apparently the timing has to be fixed in many places in the code to produce good CW at all values of TXDELAY.  If the fix were a simple one, it would have been fixed years ago.

Subject: [Elecraft] KREF3 Output Level Mod

All:

Since I'm digging into the K3 to add some options, I have decided to make the output level mods suggested for the KREF3 board when used with the KSYN3A synth. Sub-rx and internal transverter.

Just wondering why the R12 (main rx ref feed) swap from 150 ohms to 51 ohms and not the R10 sub rx feed resistor too?
Is the main rx feed double terminated with the addition of the transverter, thus needing additional drive?

Tnx,
Russ KD4JO

I have no disagreement with anything you've said, particularly
keeping the pass transistor mounting refreshed and relocating
the diodes to a heat sink if your particular RS-35(M) uses the
stud mounted diodes.

However, the 723 has a relatively high dropout threshold.  Other
regulator topologies, like that in the BWC Electronics article,
provide lower dropout and allow the pass transistors to be mounted
without insulating hardware providing for lower heat dissipation,
more efficient cooling and more reliable operation.  In addition,
the other topologies can also provide improved transient response
(resulting in improved IMD, etc. from the transceiver).

Yes, a fan is certainly useful - particularly for RTTY or contest
service.  However, I'd suggest a dual speed scheme with a constant
low speed (quiet) that switches to full speed at say 40C.  One does
not really want the heat sink (and by extension the pass transistors)
to exceed 50C.  The Astron supplies have been known to reach 85C or
more with "brick on the key" modes - certainly not good for the long
term health of the supply.

It would be nice if we could track Elecraft feature requests in a more
structured manner.  The same feature requests come up over and over again. 
We often hear, "Elecraft will never develop feature X unless N users ask for
the feature."  Rather than having subscribers respond to the Elecraft email
list saying, "Count me in", "Me too", ... why not allow subscribers to
express interest in a proposed feature by adding their name / callsign to a
"feature logbook"?  One logbook per feature request.  Logbooks would be
organized (tagged) by Elecraft product.  Each logbook would include fields
such as:

    Created by
    Created on
    Abstract
    Description
    Applicable Elecraft products
    Disposition 
    Disposition updated on
    ...

We wouldn't need to burden Elecraft with maintaining the logbooks.  We could
designate a few admins.  We would need a means of authenticating a
subscriber (e.g., Elecraft email list username / password, QRZ.com username
/ password, ...).  Any subscriber could create a new feature logbook or an
admin could create a logbook on a subscriber's behalf.  An admin would
update a logbook disposition to reflect feedback from Elecraft (e.g.,
"planned for release R", "rejected due to technical limitation T", "under
consideration", ...).  An admin would reconcile duplicate / overlapping
logbooks.  Subscribers would only express interest in a proposed feature
(not disinterest).  Comments, questions and concerns regarding a proposed
feature would be reconciled through the Elecraft email list and reflected /
updated in the logbook description by the Creator or an admin.

Thoughts?

Joe,

Why limit it just to list subscribers? Surely there are those out there who
may want a specific feature, but are not part of this list and don't wish to
be (for whatever reason) but may still own an Elecraft item?

Where are you planning to post these? Who's going to host whatever website
it is?

Just my ?0.02

73, and a firm left handshake,
John (XLX)

Hi Brian, 


The PTT problem I described is that the K3 adds a long delay (the 
VOX delay, much longer than 5-10 milliseconds) after the external 
PTT is dropped. I can't explain any rationale for adding VOX delay 
after PTT is dropped except for a firmware design error. VOX 
delay is applied to PTT in every operating mode, even in SSB 
VOX mode. 


Fortunately VOX delay is not applied when using computer keying 
via the USB port.

Frank, 
Pardon my ignorance on this issue if the below is off target. 
The asynchronous nature of an external ptt appears to be a problem. 
Suppose the K3 is in the middle of a long 100 watt dash and the external ptt signal is dropped. It clearly takes some time for the RF tail to drop to zero. One would seem to need to add some delay time for this to happen. To avoid clicks one wants a shaped tail. I dont see how the K3 can immediately go to RX. 
How fast a turn off and go to RX action do you want? Is the normal 5 ms tail fast enough? 

Of course if Winkey logic is programmed within the K3 the asynchronous problem goes away. 

The adjustable TXDELAY issue where the CW gets QSD with a setting more than 8 ms is an issue that has existed from day one. People started complaining about it on day 2. Elecraft has know about it for a long, long time. From what I am able to glean about the problem is that it may be really difficult to fix. Apparently the timing has to be fixed in many places in the code to produce good CW at all values of TXDELAY. If the fix were a simple one, it would have been fixed years ago.

1. I'm trying to reduce spam.  2. I'm looking for an element of traceability
/ accountability.  We want to discourage users from expressing interest in a
proposed feature on another user's (or users') behalf.

We'll need to work out the technical details.  At this point, I'm simply
trying to gauge interest in the concept.

Subject: [Elecraft] Backpacking antennas
Message-ID: <9eda86cd-4902-835b-969a-36e8a586e65c@triconet.org>

The recently closed thread about the so-called end-fed-half-wave (EFHW) antennas 
elicited a lot (too much in Eric's eyes) of discussion, much of it confused and 
confusing.

To keep this Elecraft related, I'll throw in something that Wayne wrote in 
another thread about the subject of this thread:

"For antennas, assuming you have trees or other ad-hoc supports available, you 
can use a random-length wire for both the antenna and ground. Toss one wire in a 
tree (etc.) and lay the other on the ground. The KXAT3 ATU will tune a 25' or so 
wire on 40 meters and up. Use twice that length to also get down to 80 and 60 m. 
You can connect the wires to a BNC-to-binding post adapter, like our model 
#BNC-BP. For wire, I recommend #26 "Silky" from the Wireman."

In the EFHW thread I made, among others, the following comment:

"This thread is a long one and frankly I didn't follow it at first, but a little 
research says that the OP was interested in bringing a coax feeder directly into 
the radio from the end of a wire.  He incorrectly called the coax a 
"counterpoise", instead of an extension of the wire which it really is, because 
it's going to radiate, but never mind that.  In this case, the antenna is a 
"sloper" whether it is called that or not.  If one end is higher than the TX 
then there is a vertical component to the geometry and the radio chassis is the 
"counterpoise.""

I've since heard privately from him (and will answer, Dan) but to help clarify 
this subject I'll turn to the late LB Cebik for help:

http://www.antennex.com/shack/Dec06/cps.html

I think his Figures 5 and 6 are particularly appropriate, but the whole piece is 
informative.

First, I admit to not understanding the problem! I do run QSK and VOX during
contest and during regular QRQ QSO's. With my K3/Alpha 9500 setup, I can run
full QSK CW up to 100 wpm and I have no PTT delay issues? I do not run with
PTT asserted and therefore I do not witness the issues other contesters
have.. As for N1MM's "poorly designed internal K3 keyer logic", I certainly
have to disagree with that comment. During 'normal' contest I operate from
28 to 40 wpm, full QSK and would go nuts if there were any perturbations
with my K3's keying. 

A so called 'solution' to CW stuttering is to purchase and use the K1EL
keyer. The real problem is with Windows op system wherein the CPU is often
interrupted to do 'internal chores'; and when this happens, all I/O ports
are shut down, which causes the CW stutter. Simply turning off the Windows
generated sound, eliminates the stutter issue and the 'requirement' to
purchase the K1EL keyer.

behavior

Okay, lets take Eric's lead and open an interesting thread directly related
to an excellent Elecraft product. 



For years many of us have suffered with the odd behavior of the K3 
in CW PTT mode. There are at least two inexplicble aspects of K3 
CW PTT behavior that have forced many of us to use external 
Winkeyers rather than the poorly designed internal K3 keyer logic 
when the K3 is in CW PTT mode. 


For CW contesters, its necessary to operate the K3 in PTT mode 
to avoid unwanted VOX delay. But for some strange reason the 
K3 always applies VOX delay after external PTT is unasserted. 
I can think of no logical reason why VOX delay should be applied 
at the end of the external PTT input when the K3 is PTT mode or 
any other mode. When PTT is unasserted, the K3 should always 
immediately return to receive mode, no exceptions. 


When using the internal K3 keyer when in PTT mode, for some 
inexplicable reason the K3 behaves like its in QSK mode. The 
only way to avoid this is to use VOX rather than PTT mode or 
to use a foot switch when in PTT mode. Both alternatives 
are unacceptable. 


The band aid solution many contesters use with excellent results 
is to avoid using the internal K3 keyer and to use an external 
K1EL Winkeyer that generates both a key output and a PTT 
signal generated according to well designed Winkeyer CW PTT 
logic. 


Why can't the K3 implement logic similar to the Winkeyer to 
generate the equivalent of "Winkeyer PTT" when using the K3 
internal keyer when the K3 is in PTT mode?

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return at the end of the week to keep this great thing going and growing.

Today was an OK day as I worked 1 station from my qth in Manitou Springs, CO.
I am running a K3 at 5 watts into an end fed half wave up about 30 feet.
Conditions were not the best but I enjoyed the QSO.

I worked:
K5PD       Dallas, TX


Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

Hi Wayne, 


As Brian pointed out, one of the design issues is that in some 
situations -- foot switch usage comes to mind -- the external PTT 
will be inadvertently un-asserted before the operator stops keying 
or stops speaking in the SSB case. The design must properly 
handle premature external PTT de-assertion. 


I recommend taking a look at the behavior of the K1EL Winkeyer. 
Its user community helped its firmware developer achieve highly 
optimized CW keying and CW PTT behavior.

Elecraft has know about it for a long, long time. From what I am able to glean about the problem is that it may be really difficult to fix. Apparently the timing has to be fixed in many places in the code to produce good CW at all values of TXDELAY. If the fix were a simple one, it would have been fixed years ago.

It should be hosted by Elecraft.


I have another radio (mcHF) that the developers take request and implement changes, it's actually a nice feature since you can see what is being requested and to a degree the status of the request.

Joe,

Why limit it just to list subscribers? Surely there are those out there who
may want a specific feature, but are not part of this list and don't wish to
be (for whatever reason) but may still own an Elecraft item?

Where are you planning to post these? Who's going to host whatever website

It would be nice if we could track Elecraft feature requests in a more
structured manner.? The same feature requests come up over and over again. 
We often hear, "Elecraft will never develop feature X unless N users ask for
the feature."? Rather than having subscribers respond to the Elecraft email
list saying, "Count me in", "Me too", ... why not allow subscribers to
express interest in a proposed feature by adding their name / callsign to a
"feature logbook"?? One logbook per feature request.? Logbooks would be
organized (tagged) by Elecraft product.? Each logbook would include fields
such as:

? ? Created by
? ? Created on
? ? Abstract
? ? Description
? ? Applicable Elecraft products
? ? Disposition 
? ? Disposition updated on
? ? ...

We wouldn't need to burden Elecraft with maintaining the logbooks.? We could
designate a few admins.? We would need a means of authenticating a
subscriber (e.g., Elecraft email list username / password, QRZ.com username
/ password, ...).? Any subscriber could create a new feature logbook or an
admin could create a logbook on a subscriber's behalf.? An admin would
update a logbook disposition to reflect feedback from Elecraft (e.g.,
"planned for release R", "rejected due to technical limitation T", "under
consideration", ...).? An admin would reconcile duplicate / overlapping
logbooks.? Subscribers would only express interest in a proposed feature
(not disinterest).? Comments, questions and concerns regarding a proposed
feature would be reconciled through the Elecraft email list and reflected /
updated in the logbook description by the Creator or an admin.

Thoughts?

Is loud fan noise common with smaller solid state amps?  I have read

set to 4 (if I recall correctly) and it is pretty quiet however setting it
one speed higher and it becomes significantly louder and quite annoying.
While I rarely use this amp I would still see a quieter fan, a setting
in-between 4 and 5 or a larger heat sink as a nice option. I wonder if the

In spite of ON4UN's 4.3, I stand by my prior statements concerning the
excellence of end-fed half wave antennas (EFHW), and their non-existent
requirements for vast counterpoise. In that specific regard, ON4UN is
unfortunately off the mark. More on that below.

Those of you using the becoming popular (?) EFHW portable antennas with
your excellent Elecraft portable rigs, you do NOT need to worry about
putting down a dense 0.35 wavelength radial field for them to work very
nicely.

I've had 50 plus years experience with 80m EFHW antennas, particularly the
EFHW inverted L or EFHWL. I, and all those I have helped install one to
improve their signal, have had very successful experience with EFHW aerial
wires. It's long-term lack of general popularity among hams has always been
curious to me. I personally attribute that to the lack of a robust
commercial **remote** tuner **made for the purpose** to go at the base. An
off-the-shelf version has always been needed to serve hams who for whatever
reason are unable or disinclined to construct these devices for themselves.

None of this 50+ years of excellent EFHW experience included a 0.35
wavelength radial field. They all included very minimalist counterpoise,
including maybe one hand's worth fed against a ground rod. I remember one
just outside a window and within a few feet of the property line. I never
recommended a ground rod, but I must admit that those worked tremendously
better than what they were previously using. And it was their house, not
mine. Who knows what kind of blowback they were getting about antennas.
Back then radio could put lines through TV signals and create next door
enemies.

I will further add that an 80 meter end-fed halfwave L, and against very
minimalist ground or counterpoise, is arguably the **best** single wire
80/75m antenna for **both** DX and local contacts, and as such a real
winner for small lot situations. Especially for those small lotters where a
hundred foot radius for Mr. Devoldere's 0.35 wavelength dense 80m radial
field runs into the street and through three or four adjacent houses :>)

At my place that would be through my house, across my driveway, through
neighbor Tim's deer fence, across his driveway and into his wife's flower
garden, and toward the back into dense woods where radials are problematic
elevated or buried.

According to Mr Devoldere, that shouldn't work.

OK. Then do this:

http://3830scores.com/editionscores.php?arg=RNfmy1zEgqmmL

On the "Sort by" line set "show" to USA and click on "go"

Do a CTRL-F on K2AV. That will be 256 Q's, 18 zones and 80 countries in a
distracted, very part-time single band effort. Not bragging (I hate
bragging along with most everyone else), but if minimal counterpoise is no
good for voltage-fed antennas, then explain that score by a distracted
decent but otherwise hardly-a-genius operator.

The antenna was an 80EFHWL over a 160m FCP flipped to 80m (explained
elsewhere). That's essentially an elevated pair of 0.125 wavelength wave
radials, +/- 33 feet. Not on the same planet as a dense 0.35 radial field.
So then how does one reconcile the ON4UN ain't gonna work text with most of
a single weekend 80m DXCC in a frequently interrupted part-time effort?

This 80EFHWL was 80m dual-use-ing my 160 inverted L over an FCP, with no
loading coils or additional radiating wires. We have proven this technique
at two other stations with excellent results. More on that, later,
elsewhere.

Back in the day I had an 80EFHWL with two 15 foot buried bare wires running
away from a basement window as a counterpoise. On 80 meters and living in
New York state, taking message traffic on the Eastern Area Net, I was one
of the handful of stations able to consistently check directly into the
Pacific Area Net and forward that traffic directly to Pacific coast
stations when the normal off-net relay failed to show up earlier on 40 or
20 meters. And that was when 4 811A's running the then 1 kW **input** legal
limit could only put about 700 watts on the antenna.

I do have ON4UN's book, and have always and still do hold him in high
regard. But he, like some number of others, have been led astray by Brown's
curious assertion about halfwaves. That's the Brown from Brown, Lewis, and
Epstein of the famous 1937 RCA study on towers and radials.

That ground current format is not duplicated in a NEC4 model of a base-fed
halfwave vertical. Brown's assertions in this regard have pretty well been
discarded as a model for ground current. Instead what you see in NEC4 has
largely been adopted. In deference to Mr. Brown, many of us (including me)
still harbor an unsatisfied curiosity as to what/where those measurements
and assertions really came from, given our very high regard for the rest of
his work.

A potential clue is that modeling a vertical halfwave **grounded** at the
base, and **fed up at the center**, DOES show the increasing current and
fields peaking out at the extremes of the radial field. Could it be that
Mr. Brown was referring to that, and somewhere in the time since, the
specification of grounded at the base got lost, thus leading to our
persisting urban myth? Alas, Mr. Brown has long since gone to the great
Radio Engineer's convention in the sky, and we probably will never know.

We must also remember that Mr. Brown was developing his theses for
**commercial** low band broadcasting, which is primarily, overwhelmingly,
interested in **ground wave**. That is where advertising-targeted customers
for local businesses lived in an era decades before the internet, Amazon,
and real customers of a "local" business were scattered all over the globe.

On the other hand, almost entirely, hams are interested in sky wave, and
consider lower angle sky wave for DX and NVIS sky wave for "close in"
coverage, not ground wave.

The point of these gargantuan BC band halfwave and fullwave antennas has
always been to squeeze out the last little drop of intensity AT THE GROUND,
to extend the range AT THE GROUND, to solidly cement the circle where for
advertising the station could verifiably claim solid signal strength to
daytime AT THE GROUND listeners. And, particularly, do that while
minimizing their 24/7 power bill.

A commercial BC station must hit a SPECIFIED signal strength (neither
higher nor lower) at various points at the ground. Getting that intensity
by improving the tower, rather than increasing the 24/7 power bill, is a
recurring cost reason for all the worry about ground wave.
Radial/counterpoise efficiency at ground relates to recurring expense. A
tower is a one-time capital expense. Long term cost/benefit analysis.

We have got to get over our bad habit of extrapolating every little nit of
the BC band paradigm into ham radio without adjustment for the large pile
of differences between their goals and needs and ours.

73, and do enjoy your EFHW's with your neat bitty Elecraft boxes. It's
about time.

It should be hosted by Elecraft. 

[js] That would be ideal.

I have another radio (mcHF) that the developers take request and implement
changes, it's actually a nice feature since you can see what is being
requested and to a degree the status of the request.

[js] Of course, new feature requests wouldn't be limited to software /
firmware.  Subscribers could request new hardware features (e.g., internal
KX3 lithium-ion battery pack, PX3 HDMI video adapter, KX2 real time clock +
RX I/Q board, ...).

[js] It's important that we have visibility not only into features in the
pipeline, but also proposed features which have been rejected.

Managing feature requests is traditional with software products.  I worked in software for 45
years prior to retirement and even started a company where enhancements to the various
products were very important to our customer base.

We had a feature request web site that we hosted and licensed customers had access to this
web site.  Prior to the web site, from 1970s to 1990s, we managed feature requests by paper
in the same manner of a customer submitting a bug report and reviewed such features with
customers during the annual user group meetings.

Given that radios, and in particular Elecraft gear, is almost just as much a software system
as hardware that such feature request management should be encouraged by Elecraft and
accessed via their http://elecraft.com web site  although not necessarily hosted by elecraft.com
since I am not sure how they manage their web site.  Access should be to anyone who has an 
Elecraft rig identified by serial number since I think being assigned login credentials should
be granted to owners only.  Yes, I know that there are Elecraft productst that do not have
serial numbers but they also are likely not to be generating feature requests anyway.

My two-bits.

Is a workaround to simply set the QSK delay to 0 in CW mode even when using PTT?

Elecraft has know about it for a long, long time. From what I am able to glean about the problem is that it may be really difficult to fix. Apparently the timing has to be fixed in many places in the code to produce good CW at all values of TXDELAY. If the fix were a simple one, it would have been fixed years ago.

I will second Guy here.
The best antenna I have ever used is the vertical EFHW. I never used a counterpoise wire, never felt that tingling in your fingers you might feel with a random wire and a metal key.
I have used 100mW to 500mW regularly with end feds with great results, single hop up to 1300 miles, 5K miles on 1W.
I say that having built all kinds of antennas and used them in all sorts of configurations, random wires, with and without counterpoises, slopers, inverted Vs, dipole, Windom, magnetic loops, quad, short whips, yagi, and except for the beams nothing beats the EFHW!
A horizontal dipole might perform as well but they are rarely high enough to perform as well, except of course for NVIS on the lower bands, and then, a horizontal EFHW will work as well.
The only antenna that came close in performance was a large magnetic loop.
Whatever the theory says, I am talking about real in-the-field performance where nothing comes close.

EFHW is a great antenna. It works but only if tuned correctly. Bad news is
 it would be difficult to do the tune job for any ATU, even the Elecraft,
due to the very high impedance ( up to the 5kohms). Please read everybody
the aticles by the EFHW guru here : http://www.aa5tb.com/efha_wrk.html.
STeve explains very clearly the whole theory behind the EFHW, the length of
"counterpoise" etc.

I have built and used many of the EFHW antennas in different configurations
, including usage of the loading coils in the multiband operations in order
to make the wire  shorter on the low bands. The tuner is the simplicity in
itself if used on qrp levels. For the higher power levels the
coil/capacitor choice must  be high ( very high!) RF voltage- proof.

Surely , the tuner , as good as Electaft makes, and the random lenght NON
resonant wire is the excellent solution for the portable work but then you
need a kind of ground whatever you can get at hand. Have tried it for many
years with the Elecraft T-1 tuner with great success working 5 W from the
hotels accross Europe tuning anything I could- window frames, rain water
pipes, random pieces of wire, :)...

Subject: [Elecraft] Feature Request: improved internal keyer and CW
	PTT	behavior

Hi Tom, 



The problems I described are unique to the K3's CW PTT mode, 
you wouldn't be aware of them if you use QSK. 


My CW keying is both from Win-Test via the USB port (it works 
perfectly) and into the K3 key and PTT connectors from the K1EL 
Winkeyer (the Winkeyer works perfectly for manual keying from a 
paddle except for the unwanted long VOX delay that the K3 applies 
to the external PTT input). 


When are you coming back to a W3LPL multi-multi DX contest to 
show us how to work hundreds of 80 meter JAs again? :) I'll 
never forget that weekend on 80 meters, its never happened to 
nearly that degree again, and certainly not on both mornings! We're 
still using the same 2 element quad at 170 feet,, but we now have 
a much better receiving antenna, a W8JI/W5ZN 8-circle receiving 
array.

First, I admit to not understanding the problem! I do run QSK and VOX during 
contest and during regular QRQ QSO's. With my K3/Alpha 9500 setup, I can run 
full QSK CW up to 100 wpm and I have no PTT delay issues? I do not run with 
PTT asserted and therefore I do not witness the issues other contesters 
have.. As for N1MM's "poorly designed internal K3 keyer logic", I certainly 
have to disagree with that comment. During 'normal' contest I operate from 
28 to 40 wpm, full QSK and would go nuts if there were any perturbations 
with my K3's keying. 

A so called 'solution' to CW stuttering is to purchase and use the K1EL 
keyer. The real problem is with Windows op system wherein the CPU is often 
interrupted to do 'internal chores'; and when this happens, all I/O ports 
are shut down, which causes the CW stutter. Simply turning off the Windows 
generated sound, eliminates the stutter issue and the 'requirement' to 
purchase the K1EL keyer.

behavior 

Okay, lets take Eric's lead and open an interesting thread directly related 
to an excellent Elecraft product. 



For years many of us have suffered with the odd behavior of the K3 
in CW PTT mode. There are at least two inexplicble aspects of K3 
CW PTT behavior that have forced many of us to use external 
Winkeyers rather than the poorly designed internal K3 keyer logic 
when the K3 is in CW PTT mode. 


For CW contesters, its necessary to operate the K3 in PTT mode 
to avoid unwanted VOX delay. But for some strange reason the 
K3 always applies VOX delay after external PTT is unasserted. 
I can think of no logical reason why VOX delay should be applied 
at the end of the external PTT input when the K3 is PTT mode or 
any other mode. When PTT is unasserted, the K3 should always 
immediately return to receive mode, no exceptions. 


When using the internal K3 keyer when in PTT mode, for some 
inexplicable reason the K3 behaves like its in QSK mode. The 
only way to avoid this is to use VOX rather than PTT mode or 
to use a foot switch when in PTT mode. Both alternatives 
are unacceptable. 


The band aid solution many contesters use with excellent results 
is to avoid using the internal K3 keyer and to use an external 
K1EL Winkeyer that generates both a key output and a PTT 
signal generated according to well designed Winkeyer CW PTT 
logic. 


Why can't the K3 implement logic similar to the Winkeyer to 
generate the equivalent of "Winkeyer PTT" when using the K3 
internal keyer when the K3 is in PTT mode?

Agree...I'm a big fan of EFHW. I have made comparisons between an HFHW with a short radial and 1/4 WL with a few radials and the EFHW beats the 1/4 WL 100% hands down. This is a great example of empirical results speaking louder than theoretical predictions.

I am downsizing to an apartment and I will not have room for a station. I am selling a K3/P3 combination, along with microphone, interconnecting cables, and manuals. Here are the details:

K3 SN 696, purchased from estate and built in 2/2007
Includes:
100 Watt amplifier
ATU
General Coverage Module
KXV3A Interface
KFL3A-500 500Hz, 5 pole filter (CW filter)
Elecraft MH2 microphone

ELECRAFT P3 (panadapter) SN 1772 purchased and built by me 12/2011

The K3 has been updated with suggested factory mods thru June 2013 and it met or exceeded all factory standards at that time. (Elecraft letter stating this available.)

The equipment is in use at my QTH now (Atlanta) and works perfectly as it has since I purchased the transceiver in 2011. All equipment is in top condition, nonsmoking environment, never in the field or mobile. Selling because I am moving into an apartment. I would like to sell both of these together. Price $2300.00 including packing and shipping in the US.

I can echo the EFHW experiences as above but, they for me, are slightly
more noisy then a quarter wave vertical. Other than that, that is my only
objection that I have to the EFHW. Every one that I have used has been
excellent.

If you talk to Balun designs they make a 52 to 1 match box that I know for
sure will easily take 800 watts CW on 40. I ran one that way and had no
problems. With power I did use a line isolator inside the shack to protect
against common mode on the shield of the coax. I had no problems with that
set up. It worked and worked well.

I have built 2 tuner boxes for them, I bought 2 old tuners that used an L
network and rewired them to a parallel tank circuit and we, my son NS0R
have used them with 1kw and had great success. No shack problems and they
radiate like a beast because the current is high in the wire and not at the
feed point on the ground. We have used them at Field Day, WPX, Sweepstakes
as our 20 and 40 meter antennas. We both work from a city lot and have no
beams. For us, using these antennas we were able to do 1400 QSO in WPXCW
with a half hearted effort.

We use the same boxes to tune half square antennas as they also have high
impedance feed points.

I personally have used a 20 meter half square...1/4 up then 1/2 wave over
to 1/4 wire elements on 20 and this will make a quarter wave on 80 that we
used with a few radials. So we got 2 bands out of one antenna. In the half
square config on 20 meters, using it as an 80 meter made it NVIS. It did
work.

I am going to have to the me a KX3 or Kx2 some day soon. I wish I had one
now because I am heading to Maine and would like to operate there into
Europe from the coast. And, you can bet I will be taking an EFHW for ease
and portability.

Hi Doug,

it works without any problems since ... I don't remember when.
But you can also buy this board with all SMT parts already soldered.

Since this was individually addressed to me as well at the reflector, I guess 
I'm expected to respond.

I will keep it brief.  I don't recall Devoldere saying anywhere in his book that 
end-fed half-waves didn't work.  Also, he wasn't advocating 0.35 lambda radials, 
he cited Brown having calculated that the current peaked 0.35 lambda from the 
base.  So you're making that up.  When contest scores become supporting 
evidence, I have nothing else to offer.

Stan,

I have built three of the resonant speakers per the QST article. I am using a K3s and have plenty of audio without an amplifier. The three speakers were all in the ballpark of 700 Hz. I took a 2 inch coupling and put on the street elbow and it resonates at about 500 hz. There might be slightly more audio coming out of the external speaker but when the resonant speaker is switched on the noise level drops enough to be noticeable so the project was worthwhile.

Earl, K4KAY

Subject: [Elecraft] (OT) Follow-up on CW Resonant Speaker

Folks, I posted about having built the CW Resonant Speaker in the February 2017 and having problems with low audio.  This is a follow-up report for those with interest in this subject.

It works!  It's fabulous!  It's unbelievable how great it sounds! CW pops out and background noise is significantly reduced.


I built it EXACTLY as described in the article and ordered the EXACT 
parts listed.  My problem was not enough audio coming from either my KX1 
or my KX2 headphone jacks.  


I purchased a fully assembled 15 watt mono amplifier - Qianson TDA2030A 
15W Mono Channel Audio Power Amplifier Board AC/DC 12V AMP Module - 
Amazon for $11.80.


With the new amp, my speaker is acoustically resonant at 760 Hz and I 
have plenty of volume; enough to fill the room.  The author had claimed 
"around 700 Hz" so it's in the ballpark.  I can verify that the 
construction article was accurate.


I wanted 600 Hz so I built a vinyl sleeve to insert into the street 
elbow and set my sidetone pitch for 600 Hz then slid the sleeve up and 
down until I got a very obvious peak in volume.


I'm still a "can fan" for serious CW operating, but it's nice to be able 
to listen to sweet CW that pops right out now that the higher frequency 
sounds are substantially subdued.


This was a really worthwhile little project.

FS: Elecraft K2, #00607, with 160 meters, SSB, audio filter, antenna tuner
and I/O modules. It has been to Don Wilhelm twice, once for all available
Elecraft upgrades, and second time to install antenna tuner and change mic
connection to Elecraft. Case has small scuffs on top and side, very minor,
would rate it 9.9/10. Electronically no issues. Includes manual and upgrade
letter. All Elecraft parts costs would be $1370, asking $900 shipped and
insured CONUS. Sold as is but guaranteed not to be DOA. Reason for selling,
have other radios for portable use.

It's likely the KX1 or KX2 have much lower audio power available than your

This was discussed in the original string. The KX2 and KX3 have 100 mW per channel of audio out the phones jack. The K3S is 2.5 W/channel.

I use this 15 W per channel stereo audio amp with my KX3. The cost fluctuates between $8 and $13 for no obvious reason. It is a deal at either end of the price range.

Subject: [Elecraft] XG3 Firmware revision 1.19 Available for download
Message-ID: <1487109951132-7626908.post@n2.nabble.com>

XG3 Firmware revision 1.19 has been released.  Use the XG3 Utility to copy
the files from the Elecraft FTP server and perform the download to your XG3.  
You can get the latest version of the XG3 Utility from our website:
http://www.elecraft.com/XG3/xg3.htm#xg3util

This revision has the ability to use 'meta-characters' in the 'W' command. 
Previous versions only allowed meta-characters  to be used in the Morse
Memory feature.   This new feature allows a user to connect their XG3 to a
PC via the XG3 Utility and create multiple command sequences using the
'Command Tester' Utility page.   Please refer to the XG3 Product Manual for
more information regarding Morse meta-characters. 

Release notes: 

Revision 1.19 February 6, 2017

?	The serial command ?W? can now interpret the same meta-characters that the
Morse memory (WM) command utilizes.  This allows the XG3 Utility?s Command
Tester to invoke a variety of complex macros using the programmable buttons
in the Utility.  Macros executed via the ?W? command can contain up to 93
characters. 


Very 73, 

Paul N6HZ

Subject: [Elecraft] K3S Receive Settings on WSJT-X
Message-ID: <1487110359985-7626909.post@n2.nabble.com>

I am operating MSK144 on 6 meters.  I have a fairly high noise level which
requires use of AGC, NR and NB to get the noise level down on other modes. 
But, if I understand correctly, I shouldn't use those features on WSJT-X. 
That leaves me with that noise level.  

I would be glad to know what settings other K3S users employ on WSJT-X.

Thanks,

John

Ameritron does not make a band switching cable for this combination.  Does
anyone have information for me to make or modify a cable?  The combination
works great but I sure miss the automatic amplifier band switching.  I have
the KX3 and the KXPA100 (using the KXPA100 utility command tester) both set
at 9600 baud because the ALS-1306 only accepts 9600 baud but I don?t
understand serial cables very well and the ALS-1306 does not use a standard
straight through cable or a null modem cable either.  It uses custom
proprietary cables for different radios.

Look at the Kenwood cable and pay attention to the TxD/RxD/Ground
lines.  Match them up to the TxD/RxD (unused)/Gnd lines on the
KXPA PC interface.

Alan,

The KXV3B has a built in 2nd preamp.  The KXV3A does not.
If you had need or desire for the external 12/10/6 meter preamp, it was 
brought on-board.

No upgrade kit is available.

A long time back someone was selling the "finger dimple" as an after-market

Hi Wayne, 


I made an error in my original email. PTT releases immediately 
in CW PTT mode regardless of VOX delay. 


Its only in VOX mode that PTT release is delayed by VOX delay, 
which makes no logical sense to me.

I have my KPA500 fan set to NORM,it has gone to fan speed 6 once, when doing RTTY one day,at 500 watts out for an extended time.I almost jumped out of my chair when it got to that speed. 
I lowered the input power to the amp and at 400 watts out never heard it that loud since.

I have no complaints on a fan working when I am using the amp hard.For SSB it is rare for the fan to go to speed 3. :) 

I really really like this amp, yes I would like a larger version. 
I would like 40 acres of property and better antennas too.

I'm really confused now [a not uncommon state for me].  I have "mature" 
K3 S/N 642.  The VOX delay is adjustable by holding the SPEED/MIC knob.  
There is a separate delay for CW and SSB.  I normally run QSK, but I 
just tried semi-breakin now and the two modes have two different 
adjustable delays.  I use a Winkey-3.  I used to use the internal K3 
keyer, and I don't remember any problems then either.  Before I got the 
KPA500, my amp wouldn't do full QSK so I ran semi-breakin all the time.

The subject of the original email doesn't note the Elecraft product, if 
it's not a K3 [or K3S I guess] disregard this.

Hi Fred, 


I never operate QSK, my amp relays aren't fast enough and they 
make too much noise. Like many K3 users, I always use either 
CW VOX or CW PTT. 


The K3 works fine in CW VOX mode, except for the odd behavior 
that after PTT is released the VOX delay continues to keep the 
transmitter active until the delay set by the Delay pot times out. 


Its a different story in CW PTT mode (not QSK). PTT is very 
responsive (the transmitter always releases immediately after PTT 
is released regardless of delay pot setting). The problem is that if 
you use the internal K3 keyer in CW PTT mode, the radio actually 
transmits in QSK mode risking damage to slow amplifier relays. 


Like many K3 users, I solved the internal keyer problem by using a 
K1EL Winkeyer connected to the K3 Key and PTT inputs. That 
solution works exactly the way the K3 should work if the logic for 
the K3 internal keyer worked as it should.

The Elecraft website forwards us to www.ftdichip.com 

This page has a lot of text but it is not clear where to get the download.? Can someone provide a link to the actual driver file.? I am using a Win10-64 laptop, although I still prefer the older laptops with serial ports.
Thanks

The solution for operating full QSK with a non-QSK amp is the QSK-2500 (http://qsk2500.myfreesites.net/).

See QST Product Review in September 2016 issue.

Hmmm ... explain what "CW PTT" mode means, that may be the cause of my 
lack of understanding.  With VOX enabled, QSK off, and using the 
internal keyer, my K3 reverts to receive on the delay time I have set 
for CW.  I tried it with a minimum delay [whatever 0.00 sets] and it 
drops immediately, between letters and sometimes even between code 
elements if I get a bit sloppy with the paddle.

Obviously, I'm doing this different than you are.

Subject: [Elecraft] P3 Product suggestion
Message-ID: <CAF==Uf3+ke-UgJk8iujmrp88Nv0Pvo665=7V8McMEfzmqPGiTg@mail.gmail.com>

The recent thread titled "P3 Point and Click" got me thinking...
I have a base model P3 (no VGA board or TX monitor). I really like how
smoothly it integrates with the K3. It has replaced the Softrock and
software panadapter that I had been using, with much less complexity- it
just works.

However, I do sometimes get frustrated with the 'twist and tap to QSY' user
interface. It is far too easy to accidentally rotate the knob in the
process of tapping it, and making a large excursion in frequency takes much
longer than a mouse point/click would.

My humble suggestion/wish would be for a whole new alternative product -
let's call it the P3x. The P3x would be a small box with IF in, VGA Out,
serial in/out, and a USB port for a mouse.  The user could supply their own
monitor in a size of their choice. It would basically be the same
electronics as the P3, but without the screen, controls, and big (mostly
empty) case.

All the normal P3 controls would be replaced by on-screen buttons with
dropdown menus where appropriate to set parameters like SPAN, etc. Perhaps
the mouse wheel could be incorporated in place of the knob for adjustments
like REF LVL. Of course, "Point and Click QSY" would be supported.

For extra credit, support for a 'gaming mouse' could be included (one of
those mice that has several additional configurable buttons) to support the
standard P3 buttons for those who prefer tactile buttons over clicking
on-screen controls.

To me, this would be a great alternative to the current P3, as it provides
the same excellent integration with the K-line, plus the choice of display
size AND mouse support.  I suspect that many ops who add the SVGA option to
their P3 do so simply for the larger screen, which makes the P3's own
screen redundant anyhow. It also seems odd to me to reach for the P3
controls while looking at the external monitor, so having the controls
integrated on screen with mouse control would be more natural.

While I'm dreaming, I'd also like it available as a P3i - same as the P3x,
but built as an internal option for the K3/K3s. OK, I have no idea where
that could fit in a fully loaded K3/K3s, but this is only a dream, after
all...

So, maybe I'm the only one who thinks this would be a great addition to the
product lineup...but there's my idea. No need to pay me royalties, but I'd
like SN 001 please :)

Slightly off topic but definitely ham radio oriented and my only ham radios are all Elecraft gear.

I am looking for stranded copper hookup wire, say #20 to #24 with very flexible insulation.  I have some of this now, like about 7 inches, but I need more.  I do not know any brand names or even what this is called.  A friend of mine thought it might be the Teflon insulated wire.

Can anyone suggest some brand names or products that I can search on-line?  Out-of-band responses please to keep this OT topic from crowding up the forum.

Thanks,

WIN10 should have the driver. I've used 3 different Ein10 installs and never needed to find a driver.

This would be quite nice. Add better than SVGA resolution and now we're
cooking with gas. Touchscreen monitor support would be the bee's knee's.

As for the integrated version, maybe we will see that in a K4 or whatever
the next radio iteration is called? I would definitely be interested!

There's tremendous commonality between the P3 and PX3 code base.  The same
will be true for your P3x.  Mouse support is trivial.  I'd simply push for
mouse support in conjunction with the P3 / PX3.  You'll get it for "free"
with your P3x.

I'd go for something like this.  The problem I have with the P3 is that
it's a great concept packaged in a pre-2010 UX and we're encroaching on the
year 2020.  .  One tweak to the suggestion:  It's shouldn't be VGA out -
that standard and associated video resolution is dead as dead can be. It
needs to be stepped up to a modern video monitor interface and resolutions

In other words, you are saying that the AMP KEY output follows keying and not PTT?

There are some really nice 12V HDMI/VGA/NTSC/PAL screens 
available. For example: <https://www.adafruit.com/products/1287> 
and <https://www.adafruit.com/products/1667>.

I like HDMI because it carries audio and video. YMMV.

Hi Fred, 


CW PTT is the K3 CW operating mode when VOX is off and 
QSK is disabled. 



Two distinct categories of messages are sent during CW contests: 


-- prerecorded messages (CQ, exchange and end of QSO messages) 
They're usually stored in an external computer so that they can 
be instantly started and prematurely stopped by the contest 
logging program if necessary. 


-- real time operator originated messages, keyboard or paddle sent 


For pre-recorded messages its important that the transceiver 
switch from transmit to receive in less than the timing for 
one Morse inter-character space (three Morse elements). At 
35 WPM an inter-character space is approximately 100 milliseconds. 


Transmit-to-receive switchover longer than 100 milliseconds will 
frequently result in the receiver not being active when the other 
station is sending the first Morse element of his callsign, 
resulting in a mis-copied callsign or a request for a repeat. 


In order for a K3 to meet the 100 millisecond transmit-receive 
switchover requirement for pre-recorded messages, the K3 can be 
operated in QSK mode, CW PTT mode, or CW VOX mode with 
front panel VOX delay set to near zero. 


For real time operator sent messages (e.g., requests for repeats 
or brief text messages) the transmit-to-receive changeover timing 
isn't as critical and a 200 millisecond VOX delay is usually acceptable. 


Many contest operators prefer to use a paddle to send real time 
messages, some use a computer keyboard. If the internal keyer 
in the K3 is used to send real time messages, only QSK can be 
used with the current K3 implementation of its internal keyer. 


If CW PTT is selected by the operator, unfortunately the K3 
actually sends the message in QSK mode. If the operator selects 
CW VOX mode, a very short VOX delay will result in VOX 
dropouts between every character and word. If the operator 
increases the VOX delay to at least 250 milliseconds to avoid 
inter-character and inter-word dropouts, the 100 millisecond 
transmit-receive switchover for real time messages cannot be 
achieved because unfortunately the K3 adds a VOX delay to 
the end of the computer generated PTT when the K3 is in VOX 
mode. 


One solution is to operate the K3 only in QSK mode, but many 
operators prefer not to use QSK. 


A very effective solution is to use an external K1EL Winkeyer 
and not use the internal K3 keyer because of its unacceptable 
behavior for contest operation. 


Perhaps the most desirable solution is to correct the shortcomings 
of the current K3 internal keyer and eliminate the unwanted 
VOX PTT delay so that K3 behavior is similar to the Winkeyer.

Hmmm ... explain what "CW PTT" mode means, that may be the cause of my 
lack of understanding. With VOX enabled, QSK off, and using the 
internal keyer, my K3 reverts to receive on the delay time I have set 
for CW. I tried it with a minimum delay [whatever 0.00 sets] and it 
drops immediately, between letters and sometimes even between code 
elements if I get a bit sloppy with the paddle. 

Obviously, I'm doing this different than you are.

Hi Vic, 


Yes, if you place your K3 in CW mode with VOX off and QSK off, 
the amplifier key output turns on and off during every Morse element.

Hi K2 users;

 

We all now that the digital interface realised especially for the K2 by
EA3BLQ in past,is SK despite !

A lot of time is gone,but are there some alternated suggestions,about the
building concept of EA3BLQ.

I can imagine that someone has continues his PCB art work for further K2
digital interface users .
I personally not need for my own purpose.

I do have build a ON4AEF external digital interface for my own into a second
K2 box (Don W3PFR now about my concept hi) .  

But a friend of mine who also have a K2 and he like to build a digital
interface circuit for his K2 like EA3BLQ has build.

He prefer the design of EA3BLQ but he needs some PCB's of Pedro.

>From there my request if someone has some dupes EA3BLQ boards or are there
some copies released around his project hi ..



Kindly regards es thanks anyway

Hello,

I wouldn't bother with a J-Pole type antenna for HF. The only one I made
remotely close was a Slim Jim for 6m, with ladder line. It worked well.
Making an UNUN for an end-fed is much simpler. All it takes is one
toroid and one capacitor if you want it to be adjustable.

My favorite portable antenna now is a 9:1 EARCHI UNUN, a 19ft wire and a
6m fishing pole. It's not a half wave but it works well down to 40m. If
I can find a tree then I throw a half wave wire and tune it with my
Ilertenna end-fed tuner. There is only one "tie-up" point, very
practical and gives me a low radiation take-off angle.

Except for 80m I'm done with horizontal antennas, especially in the
field. It's just too hard to get them high enough and the results are
never as good as an EFHW.

The only instance I would use a counterpoise wire with an EFHW is if my
coax cable (RG-174) is shorter than 25ft. Otherwise it doesn't make any
difference that I can tell.

If it doesn't have it natively, you can pull it from Windows Update. Find
the device that's not working in device manager, right click and pick
'update driver'. One of the options should be 'Search automatically online'.

Can someone provide a link to the actual driver file.  I am using a Win10-64
laptop, although I still prefer the older laptops with serial ports.

You might think about buying some 8 stranded rotator cable and stripping
out the outer bundling insulation. Most likely you might even have a few
feet of that in the old junk box. And, You will get 8 colors.

Curiously, this suggested black box version of the P3 is exactly what I was
hoping for when the concept of a P3 was announced (leaked??)

The only time I even LOOK at the P3 screen itself is to occasionally glance
at my transmitted envelope.
I use its button controls but could do without the actual P3 screen,
assuming all the info was displayed on the external monitor.

And a big "heyull yes" for the HDMI output, maybe even 4K format too if the
processing can handle it???

Asked Elecraft Support, and Wayne directly, some weeks ago about a company
maintained "public" Product Feature Request list - No specific reply so I
assume company not interested in making information on suggestions they
receive available. Any feedback collected via this forum might be helpful
but a Customer/Company reconciled and consolidated list would most likely be
best.

Also mentioned that a similar database for known firmware defects would be
useful. I reported at least 3 possible issues related to the KX2 and know
from professional experience that to accurately document and report
suspected issues can take significant time - An ongoing, up-to-date list of
Elecraft acknowledged problems would help Users avoid wasting time
investigating perceived problems. And make Customers more prone to report
potential issues - Everybody wins. And BTW, this includes documentation.

Additionally, a firmware upgrade/fix release schedule for known defects
might also prove useful.

Yeah after hitting send on the original post, I had the same thought about
HDMI instead of SVGA. Absolutely.
I also thought about the touch screen idea, but that's readily handled by a
touch screen with mouse emulation.
I think my biggest problem with the concept that I haven't completely
thought through is the fact that now I'd have TWO mice next to my keyboard,
in addition to the paddles and maybe someday a kpod. It's getting crowded
and with two mice, my chances of grabbing the wrong one would be
approaching 90%...
I'm willing to live with it :)

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return at the end of the week to keep this great thing going and growing.

Today was an Great day even though conditions were noisy with QRN. I worked 4 stations from my qth in Manitou Springs, CO and only called CQ once. What fun!
Today I used a newly acquired mcHF SDR QRP Transceiver Kit by M0NKA built by Steli, AE6OR. I ran 5 watts into an end fed half wave up about 30 feet.
Check out the mcHF at http://www.m0nka.co.uk 

I worked:
W3KC	CHARLES in DAMASCUS, MD
K5PD	PETE in SUNNYVALE (DALLAS), TX
W4MJE	JIM in MOBILE, AL
KD9VT	DAVE in SILVIS, IL

I appreciate the skills and patience of all the station operators who contact me. It makes getting up so early here worthwhile. 

Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

In a competitive business environment  especially where you are viewed as an
innovator, having a public prioritized list of potential new features could
negatively impact a company.  I think Elecraft has done a much better job of
responding to customers requests than most all Amateur radio suppliers.

I too would like to see a mouse click QSY, for reasons others have mentioned plus one.  It would be far faster, and it could be more accurate.  The knob on mine is cruder than the K3's own encoder, requiring a bit of fiddling to get it right on.  In addition, when I press the knob sometimes the whole P3 moves backwards.  I suppose I could strap a brick on top, but a wireless mouse would look better.

Hi Richard, 


The K3 and external K1EL Winkeyer is a great combination, it corrects 
most of the deficiencies of the internal K3 keyer and PTT VOX delay. 


Hopefully the next next upgrade of the K3 internal keyer will at least 
make it better, if not perfect! The biggest faults are: 
- VOX delay added to the tail of the PTT signal when in VOX mode 
- inability to use the internal keyer in CW PTT mode, it always reverts to QSK 


Thanks for your wise observations!

Frank, 


In a nutshell, what you would like is PTT control when the CW comes from the computer (via the straight key jack), and VOX when the paddles are used (via the paddle jack). 


OK - but it may not be quite as simple as it seems. Not that it cannot be done, but it might not be quite so easy to program and debug. 


First off, some users might want VOX from both inputs (in particular, someone using QSK probably would). So, this looks like a new configuration option - VOX from the paddle input only, but not from the straight key input, vs. the standard option with VOX enabled on both inputs. OK so far. 


Suppose you are using the paddle and want to continue directly with a computer message. If you hit the function key before the VOX has dropped, the computer will assert PTT and the rig will stay in the transmit state, but you will want the VOX delay to be disabled for the duration of the computer message, i.e. the firmware has to remember not to impose the VOX delay, whereas it would have done so if you had not hit the function key. The state machine is getting a bit more complicated. 



Now, what happens if the operator wants to interrupt a computer message by touching the paddle? Using a Winkey, touching the paddle aborts the computer-generated CW. If you want to be able to do this, then touching the paddle will have to turn the VOX delay on and temporarily disable the straight key CW input. Meanwhile, the computer has no way of knowing what has happened, so it has not dropped PTT. If the paddle input plus VOX delay ends before the original PC message is finished, the computer will still be asserting PTT and toggling the CW line. You will want the rig to continue to ignore the straight key input until the computer releases PTT - but in the meanwhile, do you also want the rig to be ignoring the hardware PTT from the computer and switching back to receive, even while the computer is still "transmitting"? This could get messy. Maybe the easier choice would be not to allow paddle input to interrupt the computer keying, so you have to hit the Esc key before using the paddle. Simpler to implement, but not nearly as convenient as using a Winkey. 


Add to this the fact that the interaction between CW and PTT in the K3 has always been somewhat problematic (witness the CW problems when the TX Delay setting is changed from the default 8 ms); throw in the fact that somehow this has to work even when computer PTT is done via software commands rather than a hardware signal (this has historically been a significant problem area for the K3 that was addressed in F/W revision 5.46 after significant testing effort); and maybe programming and debugging this might just turn out to be harder than it looks. 


Maybe the easiest solution is just to use a Winkey after all!

Good Morning Gang,

I'm looking for a used or out of service hex beam or similar light weight 20m~10m hex beam or similar.

I have a mast up, and a rotor, and have been looking at building a W8JK beam, but thought I'd just ask if there was anything out there that needed a new home before starting another project.

Thanks & 73

If it doesn't have it natively, you can pull it from Windows Update. Find
the device that's not working in device manager, right click and pick
'update driver'. One of the options should be 'Search automatically online'.

WIN10 should have the driver. I've used 3 different Ein10 installs and never

Can someone provide a link to the actual driver file.  I am using a Win10-64
laptop, although I still prefer the older laptops with serial ports.

Yup, I am using a WinKeyer USB with a K3S and ACOM 1500. 

The WinKeyer is driven by N1MM+ and by paddles.  I run the K3S in QSK mode.  The K3S controls the amp key line.  Works great; no problems whatsoever.

Do you have specific questions?

I do not have a K3 but if you decide to use the WinKeyer USB let me know I have a basically brand new one I would make you a great deal on. 

I used it a bit and it worked great but I just do not have a use for it any longer.

It sure would be awesome if a user could put the internal K3s keyer into a
Winkeyer emulation mode. The majority of logging software supports K1EL's
command set, but not all support the Elecraft command set.

Most (/all) software will expect to talk to the WinKeyer on a separate
serial port from the rig, so for that to use useful, you'd have to
come up with some way to combine the traffic from/to two virtual
serial ports into one real one. It's probably doable in software, but
maybe non-trivial....

I don't think the suggestion is to emulate a WinKeyer to contesting 
software, but rather for the internal keyer to have the same logic as 
WinKeyer when you send with a paddle and for the amp keying line to 
behave like the WinKeyer when sending either with the paddle, or from 
the computer via the straight key jack or the DTR line.

Right, Frank?

This is getting harder to understand than organic chemistry was.   See 
interspersed questions and results of trying to duplicate. Somehow, 
keying an external amp has come into this, the issue I've been trying to 
duplicate for you was excessive delay in going back to receive.

With VOX and QSK off, I can step on the footswitch [or plug the Winkey 
PTT output into the K3 PTT jack] and transmit.  When done, either 
reverts to RX essentially instantly.  The Winkey may hang just a tiny 
bit, very hard to tell.  I will fire up the WK3 Tools program and see if 
there's a delay programmed in.

Yes, I operate a lot of CW contests and events, both manually with 
pencil/paper logging [just to add some interest to what otherwise 
becomes mechanical], and with N1MM+ [when I care about a score].  I'm 
somewhat familiar with the protocol.

I can't make this happen on my K3.  VOX off/QSK off, the K3 reverts to 
receive as soon as I release PTT. I use the footswitch on SSB and I've 
used the CW+SSB option occasionally.  Works exactly as advertised.

Hmmm ... "unacceptable behavior for contest operation?"  There are 
several thousand K3's out there, many in contests, and a number of 
DXpeditions have used them.  That's a fairly broad assertion considering 
how common they are and how long the K3 has been around.

When keying the K3 using RTS/DTR from N1MM+, Windows will very 
occasionally lapse into 90 WPM Klingon, almost always at exactly the 
worst time, of course.  That's why I went to the WinkeyUSB.  I'm 
left-handed but I normally send right. However I have a second paddle on 
the internal K3 keyer on the left and I switch often in a contest 
depending on which hand is free.  They seem to work exactly the same for me.

I thought I might be able to help but that does not seem to be the case 
here.  I'll defer to others who understand what's going on better than I do.

I also would agree with this suggestion for a mouse function to the P3 for ease of QSY. The marker/dial and tap (push) button function?on the P3 is OK for casual QSYing. But in a contest situation, especially CW, pointing and clicking on a signal would be much faster and I would think far more accurate. I know I would use this a lot. 
I thought I read another post earlier that from a firmware standpoint it would require some additional lines of firmware. If that's the case, sounds like a relatively quick enhancement? 
?

I too would like to see a mouse click QSY, for reasons others have mentioned 
plus one. ?It would be far faster, and it could be more accurate. ?The knob 
on mine is cruder than the K3's own encoder, requiring a bit of fiddling to

Message-ID: <5A750BF323B64D6A8EFB778408E04DB7@DougTPC>

Dear OMs and YLs,

       This is just to relate my experience and observations after using my
KX2 sn 1000 in Tenerife for the past week.    This operation was just a side
event while travelling with my XYL - just a bit of fun.    Previously a KX3
was used for such operations but for me the KX2 has advantages:
1) KX2 is smaller and lighter.
2) The battery charge is much faster taking about an hour maybe two rather
than up to sixteen hours.
3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery
from Elecraft.   One battery was in the radio in case airport security
wanted me to turn it on - they did not plus the spare tucked neatly into the
KX2's larger carry case.   Airport security did not question the second
battery.  Some people have complained about vulnerable speaker wires when
opening the KX2 but for me the KX2 is less vulnerable to damage than the KX3
ribbon cable.   Taking the batteries in and out is also much easier with the
KX2.

I feel like a kid with his first BB gun. Real nervous every time I pull the
trigger. But so far things seem to be working as they should.

I hooked the Flex 6500 through the KPA500 to the KAT500 after doing all the
setup stuff. My supply voltage is 120.7 VAC and HV reads 73.7 until I key
down. I used the yellow tap. It drops to 54 V which seems kind of low. The
book says less than 60 volts with reduced output power and as low as 40.
Not sure if I should move the tap from yellow to red. I'll leave it on
yellow for now.

A quick test of input vs. output shows around 14 A max:

in    out
10    190
15    290
20    380
25    460
30    520

That was on 40 meters. On 20 meters the output is a bit lower with 500
being reached at 35 in. I'm setting the rig's max out to 35 watts.

I'm not using DDUtils or the new USB band data stuff from Flex quite yet. I
just have the basic setup of keying and letting the auto-band detect do its
job. So far so good I think.

Still some testing and getting over the nerves left to do. The antenna is a
dipole except hex on 20.

Did anyone else almost jump out of their chair the first time the KAT500
tuned up? I'm having a good day! :)

Ken, From what I know, sounds like the line voltage may be low when keying down.  Measure it with the amp running if you can.  If it stays steady, you are ok.   I don't know your house wiring and fusing, check that.  #14 wire is good at 15 amps at the breaker and #12 is fused at 20 amps.  If the line voltage dips and nothing blows in the fuse box given these numbers, then might moving the tap.  The manual is clear on settings.  Depending on the line load and the house wiring size and fusing, then you might have to do a bit more.  My line voltage is closer to 125V and fused at 20, the amp stays above the 60 volts always and I run full power with SSB.  I left the default on my factory KPA500.  I think it comes set at the higher voltage.

Hi Bill.

A Fluke plugged into the same outlet shows 120.0 VAC unkeyed and 116.9 VAC
(60 V internal) keyed with 190 watts out. 114.4 (55 V internal) with 500
watts out.

This is CW.

I could drop the tap down to RED (106-115 VAC). I kind of feel I'm on the
borderline. I'm trying to get a buddy to listen for my signal to see if
there's any anomalies he can identify. I'm getting a low hum at key down
but reading the book that seems about normal. Nothing bothersome.

Subject: [Elecraft] KX2 v KX3 for air travel and hotel operation
Message-ID: <C11F88D68CAB46F1B68DEB4ABB5D7882@DougTPC>

Dear OMs and YLs,

 

       This is just to relate my experience and observations after using my

KX2 sn 1000 in Tenerife for the past week.    This operation was just a side

event while travelling with my XYL - just a bit of fun.    Previously a KX3

was used for such operations but for me the KX2 has advantages:

 

1) KX2 is smaller and lighter.

 

2) The battery charge is much faster taking about an hour maybe two rather
than up to sixteen hours.

 

3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery

from Elecraft.   One battery was in the radio in case airport security

wanted me to turn it on - they did not. A second spare battery was tucked
neatly into the

KX2's larger carry case.   Airport security did not question the second

battery.  

 

4) Some people have complained about vulnerable speaker wires when opening
the KX2 but for me the KX2 is less vulnerable to damage than the KX3

ribbon cable.  Taking the batteries in and out is easier with the

KX2 than the KX3.

 

     For twenty QSOs the battery was only recharged once this took one hour.
The power level was 5 Watts with the display light turned off.   The antenna
was an AlexLoop which I prefer to almost anything else for holiday style
portable operations when flying.    It is a very unobtrusive antenna which
works far better than I ever expect.    The Alexloop is light and packs into
a small case provided by the manufacturer.    AlexLoop assembly is quick and
easy.   The AlexLoop was mounted on a broom handle and tied to the hotel
room balcony just placing the antenna above the wall by about a foot.    One
imagines the wall to be reinforced concrete.   The QSOs were mostly around
Europe though one QSO was made with K1RM in Connecticut and the best DX was
with WA8RCN in Ohio.

 

     I just about never bother with the QRP frequencies for such operations.
CQs are not made but stronger signals are answered.   Often I wait till a
QSO finishes before seeing if there is an opportunity.    Sometimes the
signals are too weak for more that a rubber stamp QSO but other times a rag
chew developes.   I prefer the rag chew.

 

     I am not sure how things would work on SSB as CW is my mode and has
great advantage over SSB when operating QRP into a one meter diameter
antenna.

 

      The KX3 is a better radio than the KX2 and for me the KX3 receiver
with roofing filter does a better job.   One losses 160M and 6M with the
KX2.  Though TB is my band this is just not going to work out from a hotel
room balcony.   It would be nice if the KX2 had a dimple on the tuning knob
but this is a small point.    The KX2 is not a radio for the base station
but the KX3 can serve this roll admirably.   The KX2 is a travel radio with
a great display which does all I need.

 

      Now for my gripe.   The KX2 paddle is nice and small.   I find it
handy to have the paddle attached to the KX2 when operating portable and
especially if on a park bench.    When adjusted this paddle works just fine.
It is not a Begali but the AlexLoop is not a Yagi.   The trouble is that my
KX2 paddle kept going out of adjustment sometimes with a short between two
contacts and at other times with one of the two center posts coming loose.
I am not a paddle slapper and normally operate with a close spacing and
light touch.    The KX2 paddle caused me repeated problems.   I have written
the mother ship about this and will see if my paddle can be serviced.
Earlier this month, I did note someone else having similar problems.
Perhaps the Begali Adventurer paddle with KX2/KX3 mounting bracket is a
better if more expensive option.   It is also at least twice as large but
would fit easily in the KX2 carry case.  I am just not sure if my Begali
bracket has the same problem that the original KX3 paddle bracket had with
the KX2.

 

      So this is my story.   The KX2 is a lot of fun for CW QRP operations.
My KX3 will be kept but will not travel so much.   If you are flying and
need an unobtrusive antenna consider the AlexLoop.   This antenna has done
some amazing things for me in contests with a KX3.

PS I have nothing but respect for you SOTA people.  My back and knees just
do not allow me the luxury these days.

 

PPS Sorry about previous e-mail which ran away from me prematurely.

Friends,
    Elecraft got back to me and are going to take care of my paddle.   They
have made improvements.   For one thing a blue locktite which can be undone
is now being used for the center posts.   They have also improved the way
the finger pieces mate with the gap screws.

     So I am happy about these new developments.

Nice write up. Enjoyed knowing your experiences and totally agree about the differences between the two radios.  My K3s is another atomosphere  above the KX3.   

About the key, it is mounted in a durable plastic, I would guess  to keep it light, if any of it were to experience undue stress , I would think it could cause what you are experiencing.  I have the same key and have yet to take portable, waiting for moderate weather.  Mine works just fine for now.  Since I prefer SSB I have no intention to us anything other than my N3ZN which I actually prefer to use more than the two Bengali's I used to own.  It is small, not all that light, but the adjustments match all I could do on the B.


73,

Kevin,

I would suggest that you get an electrician to check the wiring to that 
outlet and the end in the breaker box.  That sounds like too much AC 
line drop to me.

You may have to do that check on all outlets on that AC circuit.  If 
they are wired with "Backstab" connections, those connections should be 
changed to move the wires under the screwheads.
Failure to do so can result in overheating a poor AC junction, and in 
the worst case a fire.

I would attend to that matter before changing the transformer tap.

If you are calling in an electrician, you might be better off to have 
him run a dedicated 240 volt line to the shack, but while that would 
solve the problem for the KPA500, my feeling is that you still would 
have a potentially hazardous situation in the AC circuit you are 
currently using.

73,
Don W3FPR

Doug,

 I agree with you that the battery and weight is important but when you say 
that you been at the same situation with KX3 I expect some comper. 
Heard stations, reports from other hams, anttena and else from the practical work.
I think that lot of us who travell are interesting in that experience and think to switch from KX3 to KX2. 
I spent last three month travell from Europe to Canada and USA with KX3 and 
have lot of fun, not have problem with Airport security at any airport.

It is worth bringing someone in to check the lines. A 220 VAC circuit might
be part of it but I'll have what I have checked out. The entry panel is on
the other side of the house unfortunately.

I need some help.  I am down in V31 for the ARRL DX CW contest. Took the
K3 out of the carry on and the receiver is dead.  No signals received on
A/B or rcv in.  The radio did take a fairly hard hit when it was knocked
over in the case at the airport.

I have essentially take the radio apart and reseated everything but the
front panel.

I reloaded all the firm ware.

The radio has the ATU unit, dual receiver Transverter board, new syn board.

TX cal tests failed with 0 watts.

I deoxit the pins etc.

Any ideas or direction?

Both receivers are dead.

Let's assume Paul Saffren delivers Mouse-n-Click QSY support with the next P3
/ PX3 firmware release.  What else would you like the mouse to do other than
QSY the rig's VFO frequency?

I demonstrated Mouse-n-Click QSY with an Elecraft PX3 and KX3 almost 18
months ago,

    https://www.youtube.com/watch?v=D32PbJY60Uk

    http://www.wickedstone.com/KF5WBO/Mouse-n-ClickQSY.pdf

I use the mouse to control marker A (or marker B).  Tapping the left mouse
button, QSY's the KX3's VFO A frequency to the marker A frequency. 
Optionally, tapping the left mouse button also sends an ?auto
spot? command to the KX3 (i.e., automatic zero beating).  I found this to be
very effective with PSK.  With a little practice, you can Mouse-n-Click
quickly.  You just need to position the marker within the general vicinity
of your target.  The auto spot command takes care of the rest.  It's like
shooting fish in a barrel.

If I *hold* (rather than tap) the left mouse button and move the mouse right
and left, the marker A frequency *and* the KX3's VFO A frequency are
increased and decreased in one Hertz increments, respectively (i.e., manual
zero beating).  You'd have to gauge for yourself how this compares to moving
your hand between the mouse and the rig's VFO knob.

If I hold the middle mouse button (wheel) and move the mouse up and down,
the span is decreased and increased between 2, 5, 10, 20, 50, 100 and 200
kHz, respectively.  I'm effectively zooming in and out.  Obviously, a better
user experience would involve directly controlling the span using the mouse
wheel without the need to hold the middle mouse button (wheel) or move the
mouse. This would require a little more firmware.

I also demonstrated the ability to execute all of the PX3 tap and hold
functions using a mouse.  If I tap the right mouse button over a switch, the
Tap function associated with the switch is executed. If I hold
the right mouse button over a switch for longer than 500 ms, the Hold
function associated with the switch is executed. For example, if you click
the right mouse button over the Display switch, the display toggles between
the spectrum and waterfall modes.  Functions such as Display and Marker A /
Marker B execute immediately. The other right-hand switch functions require
input. I opted to use a keyboard with the mouse for input.

Any of this of interest?  How would you use a mouse (other than to QSY the
rig's VFO frequency)?

Hi Jim, 



I've never had a problem with external computer keying through the 
K3 serial port, it works fine in K3 CW PTT mode. 


My recommendation is to: 
- remove the unwanted VOX delay applied to the end of the PTT 
in VOX mode 


- Eliminate the unwanted QSK behavior of the internal keyer when 
the K3 is in CW PTT mode. Ideally the improved K3 behavior 
should be just the very well designed K1EL WinKeyer that so 
many of us are using because the K3 internal keyer is so bad.

I don't think the suggestion is to emulate a WinKeyer to contesting 
software, but rather for the internal keyer to have the same logic as 
WinKeyer when you send with a paddle and for the amp keying line to 
behave like the WinKeyer when sending either with the paddle, or from 
the computer via the straight key jack or the DTR line. 

Right, Frank?

Hi Fred, 


You can easily replicate the unwanted PTT delay as follows: 


- Set the K3 to CW mode, 
- Turn VOX on . 
- Set the VOX delay to a fairly large delay so its to observe. 
- Key the PTT line 
- You will observe the unwanted VOX delay after you unkey the PTT line 


You can easily replicate the unwanted K3 internal keyer behavior as follows: 


- Set the K3 to CW mode 
- Turn VOX off 
- Plug a paddle into the K3 
- Operate the paddle. 
- The K3 will switch from transmit to receive and the external amplifier 
key output will deactivate after each Morse element, just like it does in QSK mode

This is getting harder to understand than organic chemistry was. See 
interspersed questions and results of trying to duplicate. Somehow, 
keying an external amp has come into this, the issue I've been trying to 
duplicate for you was excessive delay in going back to receive.

With VOX and QSK off, I can step on the footswitch [or plug the Winkey 
PTT output into the K3 PTT jack] and transmit. When done, either 
reverts to RX essentially instantly. The Winkey may hang just a tiny 
bit, very hard to tell. I will fire up the WK3 Tools program and see if 
there's a delay programmed in.

Yes, I operate a lot of CW contests and events, both manually with 
pencil/paper logging [just to add some interest to what otherwise 
becomes mechanical], and with N1MM+ [when I care about a score]. I'm 
somewhat familiar with the protocol.

I can't make this happen on my K3. VOX off/QSK off, the K3 reverts to 
receive as soon as I release PTT. I use the footswitch on SSB and I've 
used the CW+SSB option occasionally. Works exactly as advertised.

Hmmm ... "unacceptable behavior for contest operation?" There are 
several thousand K3's out there, many in contests, and a number of 
DXpeditions have used them. That's a fairly broad assertion considering 
how common they are and how long the K3 has been around.

When keying the K3 using RTS/DTR from N1MM+, Windows will very 
occasionally lapse into 90 WPM Klingon, almost always at exactly the 
worst time, of course. That's why I went to the WinkeyUSB. I'm 
left-handed but I normally send right. However I have a second paddle on 
the internal K3 keyer on the left and I switch often in a contest 
depending on which hand is free. They seem to work exactly the same for me. 

I thought I might be able to help but that does not seem to be the case 
here. I'll defer to others who understand what's going on better than I do.

Good Stuff Joe. In addition to what you have suggested and done, the other thing I would like to be able to do is QSY the XIT frequency offset instead of markers A and B moving the VFO. This would be great when working a CW DX station working split usually up in a 1-5Khz window. For a QSK span within the 10Khz span range I usually just us the XIT rather than going into split mode with VFO A and B. Not sure that is easily doable though currently since marker A and B can only move the VFOs and not XIT frequency. Guess that might be an additional firmware mod. Maybe a function command in the P3 to switch markers from moving VFO freq to activate moving XIT freq would need to be added? I already have PF1 and PF2 programed to turn on XIT and move +1Khz (PF1) and +5Khz (PF2). Being able to quickly QSY the XIT with a mouse would be an advantage.

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return at the end of the week to keep this great thing going and growing.

Today was another fun day and conditions were ok till about 5:45AM then got noise for QRP. I worked 3 stations from my qth in Manitou Springs, CO this morning
Today I again used a newly acquired mcHF SDR QRP Transceiver. I ran 5 watts into an end fed half wave up about 30 feet.
Check out the mcHF at http://www.m0nka.co.uk <http://www.m0nka.co.uk/> 

I worked:
AC5P	MIKE IN BARTLESVILLE, OK
N5GW	GENE IN VICKSBURG, MS
W8SDG   MARC IN GRAND RAPIDS, MI

I appreciate the skills and patience of all the station operators who contact me. It makes getting up so early here worthwhile. 

Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

It'd be useful to change KX3 keyer speed as well, since I'm never sure about the current function of the power/speed control.

Joe,

I must have missed this as I do think that would be a significant upgrade
to PX3, perhaps
consider left click Marker A and Right click Marker B for splits when
working DX?

This is just what I was thinking about. If you can prove the concept, I see no reason as to why Elecraft can't build this into the P3. The K3 is now 10 years old; while the performance is certainly there, the basic design is now long in the tooth. When was the last time you saw a tech product design unchanged for a decade? I realize we have had software updates and internal improvements, but the outward appearance and basic function has be stagnant. This at least would offer operational functionality and a small step into current design. Don't get me wrong - I love my K3. But we are slowly watching tech design pass us by (color screen, touch control, etc).

Ken,

first-aid idea (as you said both RXs dead and Cal failed...) :

1. Turn ON K3
2. On the K3 front panel, hold CONFIG menu and turn tech mode on (CONFIG:
TECH MD ON).
3. Tap MENU to exit the menu and then tap DISP on the K3 front panel.
4. Rotate the VFO B knob to display SYN1 in the VFO B area of the display.
You should see the
status OK. the same for SYN2 status OK after...

If there is no OK status of both synths then check the all TMP coax cables
from and to the synths boards and check if synths boards seats well in the
multi-pins headers...

I have to agree about watching the tech slowly pass us by, I have also been thinking the same thing lately.

Yes I also love my K3, P3, etc but there are a few things that make it show it's age. On the P3 lack of Mouse support and the inability to connect a USB hub to allow for a keypad and a keyboard or built in Bluetooth support. ?On the K3 the limited number of macros and how the K-Pod uses all 16 of them leaving none left over for other purposes. ?As I understand it a bit of that is due to the microcontroller having limited programming space but if that's the case then the K3s should have used a more modern chip that had a larger space and possibly a new replacement board available to the older K3 to update them (something I thought that the K3 was supposed to be 100% future-proofed but with apparently not).

I built a little qrp radio (mcHF) last summer that while basically in beta really shows some promise and what a radio can be capable of. ?For a little QRP rig smaller than a KX3 it has a built in Panadapter, all mode including Digital voice ability to update the firmware by just plugging in a USB key to it etc. So the tech appears to be out there since most the issue I've seen on the mcHF is in the RF stages needing some rework etc but on the firmware side it's impressive.

But on the other hand I also just bought a K2 Kit (though admittedly I'm not sure it was my best move), what I really would like to see is an updated K2 that has to a degree been modernized since in the K2 kit some of the parts are being substituted as the originals are now obsolete, but wit a bit of updating it would still make for a nice rig.

I think there is a market for high end radios as well as smaller simpler kits (the popularity of the BiTX series of radios shows that). ?I'm not a huge fan of being tied to a computer so the Flex series does not really appeal to me. ?I had a little Flex 1500 and absolutely loved the way the filtering could be setup , but I did not like being tied to a computer so I went to the K3.
A standalone SDR rig with all the knobs and buttons seem the way to go as it gives the best of both worlds.?


Elecraft has a loyal following, though at times I believe a bit too loyal as there is a tendency to overlook things we would not overlook with other manufactures.

When I see Elecraft dodge a trivial firmware change like this year after
year, I can?t help but wonder if they have ulterior motives.  Maybe Elecraft
plans to introduce a $250 wired remote control knob.  Maybe they hope
someday the knob will control the P3 / PX3.  Maybe they feel adding a few
lines of firmware to enable a $5 wireless mouse will impact the sales of
their $250 knob.  Maybe they?re just busy.  When they don?t respond to a
feature request, it leaves us guessing.

This brings me back to my previous thread.  We need a more structured
approach to tracking Elecraft feature requests (and bugs).  We need a record
of when Mouse-n-Click QSY was first proposed.  Elecraft can come back and
say, ?The P3 / PX3 is out of firmware memory space.?  Or, ?The P3 / PX3
doesn?t have the MIPS to sample IQ, process the 1024-point FFT, update the
displays (spectrum and waterfall), field remote-control commands, ? AND
position a marker based on the delta-X field in a mouse HID descriptor?. 
This disposition will be captured along with the feature request in a
central repository for everyone to see, now and forever.   In another month
or two when someone requests Mouse-n-Click QSY, we can simply refer them to
the (now closed) feature request.  Ideally, they?d search the feature / bug
list first.

Clearly, Elecraft isn?t interested in maintaining / exposing a list of
features and defects raised by their user community.  I?ve received several
offers from members willing to host this list.  We should have something up
and running in a few weeks.

Radio community?   Do we think that we are the directors of Elecraft?    For
a moment it sounded like the K-Pod was being criticised - well this is worth

critical e-mails stimulate further design ideas.

     I am thankful not to be tied to a PC!!!  It will become obsolete.   Not
many such radios will make it into the Steam Radio Category still being used
after twenty let alone fifty years.  

     Well that is my 2 cents.    It just surprises me to hear such virulence
directed towards an amazing group of engineers with a first class company.

Perhaps they know more about the limitations of the hardware that stand 
in the way of implementing a feature you want.

1.  Elecraft is not our mother/wife/husband/caretaker

2.  Most likely, the resources are consumed by work on the K3/K3s follow-on radio which may sport many of these features.  I?d be very surprised to see much in the way of significant new updates to the K3/s and accessories.  But, of course,  I?d be happy to be surprised ...

3.  A deep breath is probably in order.

One year ago I bought a new K3S with P3, K-POD, SP3 and 500 and 200hz filters. I bought it becouse I dont needed a bell and whistles rig but a solid radio with great CW rx performance and tx with great qsk, for dx-ing, contesting and ragchewing.It satisfie all my needs.I would like only a better noise blanker and noise reduction - and I hope in next firmware releases for improvement of them.Otherwise it is perfect.Take note that those that prefer US radios want exactly this kind of radio.And accept their spartan style :)Those that want lot of gadgets, usuale opt for a jap radio, Icom-Yaesu-Kenwood, I think.Ian IK4EWX

Subject: Re: [Elecraft] Mouse-n-Click QSY

When I see Elecraft dodge a trivial firmware change like this year after
year, I can't help but wonder if they have ulterior motives.  Maybe Elecraft
plans to introduce a $250 wired remote control knob.  Maybe they hope
someday the knob will control the P3 / PX3.  Maybe they feel adding a few
lines of firmware to enable a $5 wireless mouse will impact the sales of
their $250 knob.  Maybe they're just busy.  When they don't respond to a
feature request, it leaves us guessing.

This brings me back to my previous thread.  We need a more structured
approach to tracking Elecraft feature requests (and bugs).  We need a record
of when Mouse-n-Click QSY was first proposed.  Elecraft can come back and
say, "The P3 / PX3 is out of firmware memory space."  Or, "The P3 / PX3
doesn't have the MIPS to sample IQ, process the 1024-point FFT, update the
displays (spectrum and waterfall), field remote-control commands, . AND
position a marker based on the delta-X field in a mouse HID descriptor". 
This disposition will be captured along with the feature request in a
central repository for everyone to see, now and forever.   In another month
or two when someone requests Mouse-n-Click QSY, we can simply refer them to
the (now closed) feature request.  Ideally, they'd search the feature / bug
list first.

Clearly, Elecraft isn't interested in maintaining / exposing a list of
features and defects raised by their user community.  I've received several
offers from members willing to host this list.  We should have something up
and running in a few weeks.

Elecraft is a business,?I believe some erroneously elevate them to near god like status.

I choose to spend my money (that represents hours of my life in labor) with business I believe are worth while. ?As long as Elecraft stays in-tune with their customers I will continue to spend my money with them.If they fail at delivering I will simply move onto the next vendor who is willing and able to deliver. ?
Business is business plain and simple.

1.? Elecraft is not our mother/wife/husband/caretaker

2.? Most likely, the resources are consumed by work on the K3/K3s follow-on radio which may sport many of these features.? I?d be very surprised to see much in the way of significant new updates to the K3/s and accessories.? But, of course,? I?d be happy to be surprised ...

3.? A deep breath is probably in order.

Limited Macros ???

Just a bit of information:  The number of macros was 8.  It was 
increased to 16 to support the number of buttons on the K-Pod.

Just because the K-Pod buttons can access the macros does not mean that 
those macros are dedicated to the K-Pod.  The fact that they are stored 
in the K3 allows them to be assigned to buttons as well or called up by 
an external source other than the K-Pod.

As I understand it a bit of that is due to the microcontroller having limited programming space but if that's the case then the K3s should have used a more modern chip that had a larger space and possibly a new replacement board available to the older K3 to update them (something I thought that the K3 was supposed to be 100% future-proofed but with apparently not).

I am well aware that there are 16.

But since they are all assigned to the K-Pod they are no longer useful for self reprogramming Macros.

Harry,

So use only 8 of them on your K-Pod - the other 8 can be used as 
self-programming (just don't use the buttons relating to 
self-programming buttons on the K-Pod unless you want to confuse 
yourself by not knowing which state they are in).

The point is that 8 was sufficient in the past, I am just curious why 
expanding the number to 16 would be a problem.

Z3 board came loose and probably damaged.  Removed and soldered a jumper 
re Elecraft support.  We have power.

Nothing on receive yet.  Triple checking on the tmp cables etc as I have 
had the radio apart many times.

AGC, pre amp seem to have no effect.  Receive on the xvter board is also 
dead.

Easier said than done;?Hold the tap too long and it messes up the reprogramming macro.

It should not be a problem for Elecraft to expand the macro area to hold more macros,providing they had the foresight to use a chip with a larger programming space.

Point is there is room for improvement and either they keep up or they will be passed by.

Harry,

So use only 8 of them on your K-Pod - the other 8 can be used as 
self-programming (just don't use the buttons relating to 
self-programming buttons on the K-Pod unless you want to confuse 
yourself by not knowing which state they are in).

The point is that 8 was sufficient in the past, I am just curious why 
expanding the number to 16 would be a problem.

As I understand it a bit of that is due to the microcontroller having limited programming space but if that's the case then the K3s should have used a more modern chip that had a larger space and possibly a new replacement board available to the older K3 to update them (something I thought that the K3 was supposed to be 100% future-proofed but with apparently not).

When I read posts like this (both tone and content) I can't help 
wondering a lot of things.  Probably not the same things you wonder

For a moment it sounded like the K-Pod was being criticized

[js] I didn?t mean to criticize the K-Pod.  I?m simply speculating as to why
Elecraft hasn?t added P3 / PX3 mouse support.

[js] Last time I checked, the K-Pod isn?t capable of functioning as a mouse
(and keyboard).  However, according to the K-Pod manual, this support is
planned.

[js] I?m willing to concede Elecraft may simply be too busy.  However, the
need for Mouse-n-Click QSY has been raised every few months for years.  And
it?s a trivial firmware change.  I think there?s something more to it.

I am thankful not to be tied to a PC!!!

[js] Same here!!!  Hence, the desire for P3 / PX3 mouse support *without*
the need for a PC.

Perhaps they know more about the limitations of the hardware that stand in
the way of implementing a feature you want.

[js] My point exactly (second paragraph).  Let?s capture their knowledge of
the limitations (e.g., memory, MIPS, ...) in conjunction with the feature
request.  Case closed.

I would be interested in something like that, but the log file on the shack
computer has more than 30 years of logs on it. Not really wanting to clog
up my laptop with that, so I just do the adif thing with the portable logs
then import them to main log when I get home.

According to the manual, through a future firmware upgrade, the K-Pod will be
able to function as a USB HID (Human Interface Device) such as a keyboard or
mouse.  Conceivably, the eight K-Pod tap and hold switches could be mapped
to 16 P3 / PX3 macros.  You could even implement three ?banks? of 16 macros
for a total of 48 K-Pod macros.  Of course, this assumes:  1. you have a P3
equipped with the SVGA option or a PX3; 2. you?re not already using a
keyboard in conjunction with your P3 / PX3 (this would require USB hub
support); and 3. you haven?t already burned all 50 of your P3 / PX3 macros
(unlikely).

In a nutshell, I?m assuming if the K-Pod is to function as a USB HID
keyboard, the tap and hold switches would correspond to standard keyboard
keys (including combinations of Ctrl, Alt and Shift modifiers).  The keys
would be assigned to macros on the P3 / PX3.  This wouldn?t require any
change to the P3 / PX3.  The P3 / PX3 wouldn?t be able to differentiate the
K-Pod from a keyboard (which it already supports).

With a P3, the K-Pod knob could continue to control the K3s/K3 via the data
connector.  With the PX3, the K-Pod knob would present itself as a mouse. 
Of course, this would require the beforementioned Mouse-n-Click QSY support. 
Alternatively, if you wanted the K-Pod knob to control the P3, the
Mouse-n-Click QSY support could be leveraged there as well.

As I sit and look at my station and my K-Pod, just remember Dayton is not
that far away, and Wayne, Eric and the rest of the crew have been very very
quiet. Remember they're very good at blowing people out of the water ....
remember there was a radio that came out last year that caught everybody
flat-footed  .. esp the competition.

Given the lag between the turning tuning knob and movement on 
the VGA display with the P3, there may be an issue with having 
the mouse cursor track with the mouse movement in a usable 
maner. I frequently move the frequency too far turning the knob 
and watching the VGA display.

Well, I used the starter motor on my car -- certainly a 
technological artifact -- this morning. I don't think there have 
been significant changes to the design of starter motors in my 
72 year lifetime. There have probably been incremental 
improvements in things like metallurgy and insulation, but the 
overall design remains the same.

I have two re-programming macros, Split + 1 and No Split in Macro 1 and Macro 2 
respectively. in my K3S. In the radio these are assigned to PF1.  Hold PF1, go 
to Split; hold it again, cancel split.   Now, to avoid disasters, using the 
K-Pod, I must program both tap and hold of PF1 and PF2 respectively to split and 
cancel split.  So there are four functions tied up to do what I can do with one 
button push on the K3S.  To get back to one button, I've put radio PF1 on K-Pod 
PF3. Confusing, no?

IMHO, to fulfill its promise, the K-Pod should hold the macros and send them to 
the radio.  They should be programmable in the K-Pod via USB.

As I understand it a bit of that is due to the microcontroller having limited programming space but if that's the case then the K3s should have used a more modern chip that had a larger space and possibly a new replacement board available to the older K3 to update them (something I thought that the K3 was supposed to be 100% future-proofed but with apparently not).

If the Astron ain't broke keep it. There would have to be a real good 
reason, like parts becoming unobtainable, for me to consider getting rid 
of my Astron. If they break they are dead simple to diagnose and fix and 
no chance of making noise like a switcher.

Using the Winkey is not a requirement. It's just a much better keyer 
than the Elecraft keyer.
One chip and some extraneous parts...problem gone.

Message-ID: <2FB9E60C-282F-4AD3-93E1-3888C77CFCF6@bellsouth.net>

Hi,

Just curious if others had this issue and could resolve it.

My K3S had suddenly started showing High SWR faults with resulting low power out due to rollback even when the autotune reads 1.0-1.  Different dummy loads, antennas, and coax jumpers change nothing.  I upgraded the firmware to the most current release and still no change.

Any suggestions?

I agree with Kevin's "Why"
Tell me of another amateur radio manufacturer who maintains such a list. 
  This is *not* open source programming.
If such a list exists for any other amateur radio manufacturer, they 
would come out with an "improved" new radio (Mark VI) version and if you 
wanted the "upgrade" you would have to buy the new radio.

With Elecraft, you get those "upgrades" at no cost, just download the 
firmware. You knew (or should have known) the capabilities of the radio 
when you bought it - you did review the specializations and features 
before you purchased it, did you not?

I don't think we need to have visibility into the Elecraft engineering 
resources, and prioritization of requests for added functions.

Those at Elecraft *do* listen and often respond to such customer 
requests, but the prioritization of those requests must be on Elecraft's 
terms for reasons of availability of engineering resources and the sales 
benefit of those changes.

Bug reports will get a different response than those requests for 
changed operation.  If bug reports are proven valid and repeatable, they 
will be attended to promptly.

Whether or not you hear a noise source depends on the nature of THAT 
source, in what frequency range it produces noise, its proximity to your 
antennas, and how much other noise is present in your environment.

I have made thousands of QSOs using the Powerwerx supply powering both a K3S
and a KAT500.

Is there a problem using the Powerwerx to power both the K3S *and *the
KAT500, or would I need a second Powerwerx?

Hi,

Just curious if others had this issue and could resolve it.

My K3S had suddenly started showing High SWR faults with resulting low power out due to rollback even when the autotune reads 1.0-1.? Different dummy loads, antennas, and coax jumpers change nothing.? I upgraded the firmware to the most current release and still no change.

Any suggestions?

If it were only a chip change to add a winkeyer 3 inside my K3 I would do it in a heart beat.

Subject: [Elecraft] KPA500 ALC Voltage
Message-ID: <AFD12DBE-3143-4724-B089-06735126D948@icloud.com>

Hello all,

My backup KPA500 has an issue with the ALC connection. As soon as I apply power to the amp, the ALC voltage on the connector goes to -5.2vdc. It is a ?hard? problem, not effected by any tapping or poking around that I have done so far. It takes about 3 seconds for the voltage to decay when I turn off the power at the back panel.

My other KPA500 has zero volts on the ALC until I transmit and then the voltage varies, as it should. This ALC on the ?problem? amp worked fine with a Kenwood rig (with 0 to -7vdc ALC range), but wouldn?t let an Icom rig transmit at all (Icom has a 0 to -4vdc range).

I don?t use ALC very often, but would like to have it working when I want it. Any ideas?

Thanks,
Lyn - KC8I

Although it doesn't guard against accidentally holding KPod F1 or F2, another thing you can do is assign your recursive or self programming macros (now Macro 1 and Macro 2?) to be activated by a hold of PF1 and then make another macro say Macro 16 that holds PF1 (SWH45).  That does use up another of the 16 total macros but now just tapping Kpod F8 will toggle between split and non-split

Fred KE7X

Subject: Re: [Elecraft] Tech passing us by - was Re: Mouse-n-Click QSY

I have two re-programming macros, Split + 1 and No Split in Macro 1 and Macro 2
respectively. in my K3S. In the radio these are assigned to PF1.  Hold PF1, go
to Split; hold it again, cancel split.   Now, to avoid disasters, using the
K-Pod, I must program both tap and hold of PF1 and PF2 respectively to split and
cancel split.  So there are four functions tied up to do what I can do with one
button push on the K3S.  To get back to one button, I've put radio PF1 on K-Pod
PF3. Confusing, no?

IMHO, to fulfill its promise, the K-Pod should hold the macros and send them to
the radio.  They should be programmable in the K-Pod via USB.

As I understand it a bit of that is due to the microcontroller having limited programming space but if that's the case then the K3s should have used a more modern chip that had a larger space and possibly a new replacement board available to the older K3 to update them (something I thought that the K3 was supposed to be 100% future-proofed but with apparently not).

I said below: "To get back to one button, I've put PF1 on K-Pod PF3"

I did misspeak when I said, referring to the K-Pod, PF1 & PF2, I meant F1 and F2.:-)

Why?

[js] {hypothetically} I have an idea for a new feature, P3 mouse support. 
Before proposing the feature on the Elecraft mailing list, I first go to the
Elecraft feature / defect tracking system and search for "mouse".  I find a
feature called, "Mouse-n-Click QSY".  I see the feature was created on
December 16, 2011 by Dave Perry (N4QS).  According to the feature
description, Dave replied to a thread titled "P3SVGA - Coming soon" authored
by Eric Swartz (WA6HHQ).  Dave replied, "SVGA display looks great.  Will we
also have point and click capability with a mouse?"  I further discover the
feature has been closed with the disposition, "The P3 doesn?t have the MIPS
to sample IQ, process the 1024-point FFT, update the displays (spectrum and
waterfall), field remote-control commands, ? and position a marker based on
the delta-X field in a mouse HID descriptor.?  Oh well, it was a great idea. 
But I see due to technical limitations, the P3 isn't capable of mouse
support.

Yes Joe, why should you be privvy to proprietary Elecraft information?

[js] We're not talking about proprietary information.  We're talking about
features and defects raised by the Elecraft user community.  We're talking
about the same features and defects discussed on this mailing list every
day.  The same system may track "top-secret" features which aren't exposed
to the public.  The system may serve to track internally discovered defects
which aren't exposed to the public (e.g., defects corresponding to an
unreleased firmware version).  Even publicly-visible features and defects
will have some fields and attributes which aren't exposed to the public
(e.g., assigned engineer, effort estimate, test plan, ...).  This is all
standard, vanilla stuff.

Except that you explicitly and repeatedly whined every time you brought 
it up that Elecraft wasn't willing to do those things, and in my opinion 
they have zero obligation and little practical reason to do so.  If you 
want someone to maintain such a database, do so yourself (or talk 
somebody else into it) without getting all moralistic about it.  It 
might be important to you, but it isn't important for Elecraft to do it 
for you.

Hi Frank,
I haven't followed this entire thread, but I believe there is no need for
any firmware changes, or a WinKey, to solve this problem.
The problem of unwanted PTT delay when using the internal keyer with VOX,
and computer-generated CW/PTT, was already addressed by the improvements to
the *RX;* command in K3 firmware 5.46 and later.  Sending an *RX;* command
at the end of all computer-generated CW messages will /immediately/ open the
PTT line no matter how long you set the VOX delay, so there will be no delay
in receiving when the computer-generated message terminates.   You will
still get the programmed CW VOX delay when hand-sending, and the PTT will be
held closed for the duration of all computer-generated messages, /if/ you
follow all of the steps outlined below.
This is easy to do in Win-Test, which is the contest software I think you
are using.  Other contest loggers have similar features.
This works best connecting paddles directly to the internal keyer of the K3
and avoiding the WinKey entirely.
First set *CONFIG:RTS-DTR PTT-KEY*
Disconnect the WinKey and disable its serial port.
Tell Win-Test to key CW on the K3 serial port DTR pin, and PTT on the RTS
pin (under *Options | Interface configuration*).  Win-Test sends great CW
using either real serial ports or FTDI USB-to-Serial adapters.  Or you may
use legacy LPT port CW/PTT keying circuits if you prefer (set CONFIG:PTT-KEY
OFF-OFF when using LPT keying).
Download *K3scripts.zip* from my Win-Test LUA script web site, 
https://bit.ly/wtscripts <https://bit.ly/wtscripts>  .  This contains many
useful K3 scripts, including *PTTOff.wts*, which does the following:
At the end of /every/ CW message programmed in Win-Test, call this script,
like this:
etc.
In Win-Test, the "~" character is a macro separator, like a blank, but it
sends no "space" characters.  The macro won't run until the final bit of CW
is output.
Now you may put the K3 in semi-breakin mode, with VOX ON, and set the CW VOX
delay to whatever works well with your paddling speed (0.21 works pretty
well at contest speeds).  This CW VOX delay will be /overridden/ at the end
of all computer-generated CW messages (except for Alt-K keyboard CW, but I
think that's an acceptable exception).
As a final step, make the *Escape* key halt any CW in progress /and/
*immediately* open the PTT line too.To do this, assign the following script
(name it *PlayHalt2.wts*), to the *Escape* key, using the Win-Test Scripts
Manager.
Please let me know if this solves all the problems you care about regarding
unwanted PTT hang delay, Win-Test, and the K3.

Bob, N6TV

Message-ID: <e199c4f7-0bfb-3acc-b245-81c8951ed155@yahoo.com>

My KX2 operates Pactor 2 with RMS Express and Airmail on my PTCiiUSB
modem with the KX2 ACC cable for changing frequency.  But I also want to
connect the PTCiiUSB rig controls directly to the KX2 ACC socket to
avoid having to use the extra ACC cable.  I know the PTCiiUSB allows the
Kenwood instruction set that works on the KX3 and I think it also has
the K3 instruction set.  The connections are clear and making the cable
will be easy, except that the PTCiiUSB offers the options of TTL or V24
for the RXD and TXD connections.  Does anyone know whether the KX2 and
the KX3 use the TTL or the V24 protocols and whether connecting to the
wrong protocol will cause damage?

I'd love to hear from Elecraft on this. It might be that the current hardware has reached its limits or they aren't sure how to support it. 
Based on the keyboard limitations I'd expect to require additional hardware just for the myriad driver software requirements. 
One thought I had was using a COTS (common off the shelf) microcontroller board (like the raspberry pi or such) as an interface board. The MC (microcontroller) could run open source linux to support the largest variety of drivers/keyboard setups while also providing robust I/O for the K3/P3 in addition to being able to be used as either just an interface or a complete station running logging, keyer, digitial modes..etc... which is basically what many of us currently do. 
What I've not looked into is interfacing the P3 with outputs from the MC to mimic the rotary dial functions. Depending on the P3 screen type it may even be possible to add an INPUT to the P3 to allow the P3 screen to display the MC console/screen. 

I don't have the time or gear to look at this further. It's just an idea that would require some re-engineering of the P3 potentially. Heck I could see adding the MC inside the P3 case directly. 
Just randome thoughts.

I also would agree with this suggestion for a mouse function to the P3 for ease of QSY. The marker/dial and tap (push) button function on the P3 is OK for casual QSYing. But in a contest situation, especially CW, pointing and clicking on a signal would be much faster and I would think far more accurate. I know I would use this a lot. 
I thought I read another post earlier that from a firmware standpoint it would require some additional lines of firmware. If that's the case, sounds like a relatively quick enhancement?

I too would like to see a mouse click QSY, for reasons others have mentioned 
plus one.  It would be far faster, and it could be more accurate.  The knob 
on mine is cruder than the K3's own encoder, requiring a bit of fiddling to 
get it right on.  In addition, when I press the knob sometimes the whole P3 
moves backwards.  I suppose I could strap a brick on top, but a wireless 
mouse would look better.

Chris,

I believe you could use either.  Their should be no damage to the KX2 if 
the V24 levels are used.  To be safe, try TTL first - if it works, use 
it.  If not, switch to V24.

In looking at the Elecraft goodies page today I notice they now offer the KXPD3 (KX3 Paddles) which ?include improved dot/dash paddle connection wires?.

Has anyone had experience with this improvement?  My paddles are so unreliable as to be useless in spite of receiving the factory mod which I believe amounted to better plating on some parts.

Is this offered as an upgrade?

I know others have described adding fine wires to solve the problem but I considered the procedure beyond my skills.

I agree fully with Don and Dave (messages below) and others who have made similar points.  To me it?s very simple:  We are customers, not shareholders.

There are features I wish their products had, and I have had no hesitation to mention them on this reflector.  Perhaps uniquely among producers of the type, as I understand it Elecraft monitors these posts.  If an idea has merit, acquires some me-toos, and would work within the financial and technical framework of the company and its processes, I have confidence it will be considered.  But I do not believe the company owes me even so much as an acknowledgment.   No more than I owe them an explanation about why I haven?t yet bought a KX2.  Elecraft is a very good amateur radio equipment maker.  I am a happy repeat customer.  So long as I like their gear and their service, I?ll keep buying it.  If it were a publicly listed company I might very well buy stock in it.  But it isn?t, and I haven?t.

    I agree with Kevin's "Why"
    Tell me of another amateur radio manufacturer who maintains such a list. 
      This is *not* open source programming.
    If such a list exists for any other amateur radio manufacturer, they 
    would come out with an "improved" new radio (Mark VI) version and if you 
    wanted the "upgrade" you would have to buy the new radio.
    
    With Elecraft, you get those "upgrades" at no cost, just download the 
    firmware. You knew (or should have known) the capabilities of the radio 
    when you bought it - you did review the specializations and features 
    before you purchased it, did you not?
    
    I don't think we need to have visibility into the Elecraft engineering 
    resources, and prioritization of requests for added functions.
    
    Those at Elecraft *do* listen and often respond to such customer 
    requests, but the prioritization of those requests must be on Elecraft's 
    terms for reasons of availability of engineering resources and the sales 
    benefit of those changes.
    
    Bug reports will get a different response than those requests for 
    changed operation.  If bug reports are proven valid and repeatable, they 
    will be attended to promptly.

Phil,

Yes, Elecraft has an upgrade program in place.  Either upgrade your old 
KXPD3 or get a new one as an exchange.  Of course, there is $$$ involved.

Contact K3support to get the details.

Dear Ted and Co,
    Years ago I requested a pod to control memory and VFO.   It did not
happen and I requested again but then assumed it a lost cause and looked at
the fine K3 in front of me and the service given and decided well maybe
there is a reason and that is that.  Other solutions came out but it was
still not really what I hoped for.  Then out of the blue Elecraft brings in
the K-Pod which is far better than anything ever expected.

     In time some of the many other requested features may be introduced but
it is an Elecraft decision whether either practical or worth while.   If you
have a better radio available purchase it.

     Meanwhile I am perhaps a bit cranky but if as a company I openly
solicit suggestions the idea that they would be recorded by a third party
who would dictate to my enterprise well maybe I would be thick and stop
bothering with a reflector.

    For me the fact that Elecraft has done so much development on an
existing product and kept older versions of the product up to date is just
wonderful.    Then quietly Elecraft goes off and develops the KX2 post KX3 -
oh I will never need one of those.   Then I saw the KX2 at Friedrichshafen
and fell in love all over again.    Let us not be too critical and let us
appreciate the ability to talk to the design engineers who own and manage
Elecraft.

I agree fully with Don and Dave (messages below) and others who have made
similar points.  To me it's very simple:  We are customers, not
shareholders.

There are features I wish their products had, and I have had no hesitation
to mention them on this reflector.  Perhaps uniquely among producers of the
type, as I understand it Elecraft monitors these posts.  If an idea has
merit, acquires some me-toos, and would work within the financial and
technical framework of the company and its processes, I have confidence it
will be considered.  But I do not believe the company owes me even so much
as an acknowledgment.   No more than I owe them an explanation about why I
haven't yet bought a KX2.  Elecraft is a very good amateur radio equipment
maker.  I am a happy repeat customer.  So long as I like their gear and
their service, I'll keep buying it.  If it were a publicly listed company I
might very well buy stock in it.  But it isn't, and I haven't.  

Ted, KN1CBR

    I agree with Kevin's "Why"
    Tell me of another amateur radio manufacturer who maintains such a list.

      This is *not* open source programming.
    If such a list exists for any other amateur radio manufacturer, they 
    would come out with an "improved" new radio (Mark VI) version and if you

    wanted the "upgrade" you would have to buy the new radio.
    
    With Elecraft, you get those "upgrades" at no cost, just download the 
    firmware. You knew (or should have known) the capabilities of the radio 
    when you bought it - you did review the specializations and features 
    before you purchased it, did you not?
    
    I don't think we need to have visibility into the Elecraft engineering 
    resources, and prioritization of requests for added functions.
    
    Those at Elecraft *do* listen and often respond to such customer 
    requests, but the prioritization of those requests must be on Elecraft's

    terms for reasons of availability of engineering resources and the sales

    benefit of those changes.
    
    Bug reports will get a different response than those requests for 
    changed operation.  If bug reports are proven valid and repeatable, they

    will be attended to promptly.

Hi Bob, 


The Win-Test PTTOff script corrects the unwanted K3 PTT VOX delay! 


Hopefully Elecraft will eventually eliminate the unwanted PTT VOX delay too. 


Thanks

Hi Richard, The K3 and external K1EL Winkeyer is a great combination, it corrects most of the deficiencies of the internal K3 keyer and PTT VOX delay. Hopefully the next next upgrade of the K3 internal keyer will at least make it better, if not perfect! The biggest faults are: - VOX delay added to the tail of the PTT signal when in VOX mode - inability to use the internal keyer in CW PTT mode, it always reverts to QSK 

Hi Frank, 
I haven't followed this entire thread, but I believe there is no need for any firmware changes, or a WinKey, to solve this problem. 
The problem of unwanted PTT delay when using the internal keyer with VOX, and computer-generated CW/PTT, was already addressed by the improvements to the RX; command in K3 firmware 5.46 and later. Sending an RX; command at the end of all computer-generated CW messages will immediately open the PTT line no matter how long you set the VOX delay, so there will be no delay in receiving when the computer-generated message terminates. You will still get the programmed CW VOX delay when hand-sending, and the PTT will be held closed for the duration of all computer-generated messages, if you follow all of the steps outlined below. 
This is easy to do in Win-Test, which is the contest software I think you are using. Other contest loggers have similar features. 
This works best connecting paddles directly to the internal keyer of the K3 and avoiding the WinKey entirely. 
First set CONFIG:RTS-DTR PTT-KEY 
Disconnect the WinKey and disable its serial port. 
Tell Win-Test to key CW on the K3 serial port DTR pin, and PTT on the RTS pin (under Options | Interface configuration ). Win-Test sends great CW using either real serial ports or FTDI USB-to-Serial adapters. Or you may use legacy LPT port CW/PTT keying circuits if you prefer (set CONFIG:PTT-KEY OFF-OFF when using LPT keying). 
Download K3scripts.zip from my Win-Test LUA script web site, https://bit.ly/wtscripts . This contains many useful K3 scripts, including PTTOff.wts , which does the following: 
wtRadio:Send("RX;")
return -1 
At the end of every CW message programmed in Win-Test, call this script, like this: 
CQ $MYCALL $MYCALL~#PTTOFF
$LOGGEDCALL $RST $STATE~#PTTOFF
TU $MYCALL~$CR~#PTTOFF
$MYCALL~#PTTOFF etc. 
In Win-Test, the "~" character is a macro separator, like a blank, but it sends no "space" characters. The macro won't run until the final bit of CW is output. 
Now you may put the K3 in semi-breakin mode, with VOX ON, and set the CW VOX delay to whatever works well with your paddling speed (0.21 works pretty well at contest speeds). This CW VOX delay will be overridden at the end of all computer-generated CW messages (except for Alt-K keyboard CW, but I think that's an acceptable exception). 
As a final step, make the Escape key halt any CW in progress and immediately open the PTT line too. To do this, assign the following script (name it PlayHalt2.wts ), to the Escape key, using the Win-Test Scripts Manager. 
-- If Escape key already halted CW, and we were called back
if wtApp:IsPostKeyProcess() then
   wtRadio:Send("RX;")                 -- Send "Receive" command to K3 to open PTT line
   return -1			       -- No further keystroke processing
else				       -- Else, first time through
   return 1			       -- Request normal keystroke processing of Escape key, with
                                       -- callback requested.
end 
Please let me know if this solves all the problems you care about regarding unwanted PTT hang delay, Win-Test, and the K3. 
73, 
Bob, N6TV

Chris,

The KX2 and KX3 use 12V switching levels for sending data out its serial 
port.  It was designed to interface to "standard" RS232 serial ports.

I'd use standard RS232 levels first.  If that doesn't work, and If the 
PTC modem in TTL mode is protected from 12V levels, I'd try that next.

Lyn,

There is obviously a problem with your KPA500 ALC.
I doubt those of us here has the capability to diagnose the problem 
properly.
Contact K3support and perhaps they can guide you through some checks 
which will identify the problem area and allow you to either correct it 
or determine if you need to send it in for repair.

Hi all,

While Ed AB8DF has been on vacation I stepped in until his return and it?s been great fun. I expect Ed AB8DF will be on frequency again starting on Monday morning. Please work Ed  and maybe look for me up a Khz or so above him. 

Today was another fun day and conditions were a bit noisy. I had nice QSOs with 3 stations from my qth in Manitou Springs, CO this morning
I again used a newly acquired mcHF SDR QRP Transceiver. I ran 5 watts into an end fed half wave up about 30 feet.
Check out the mcHF at http://www.m0nka.co.uk <http://www.m0nka.co.uk/>  or the EFHW antenna at http://myantennas.com/wp/product/efhw-8010p/ <http://myantennas.com/wp/product/efhw-8010p/>
(BTW? no affiliation with the above products but enjoy them)

I worked:
K5BGB	ROD IN BRYAN, TX
N4ELM	DAVE IN LAFAYETTE, LA
W5YB	ALEX IN ABIQUIU, NM

I appreciate the skills and patience of all the station operators who contact me. It makes getting up so early here worthwhile. 

Ed will be hanging out on 3.560 most weekday mornings from 1200z to 1300z and I will be about a kHz above him.
while we have morning coffee.
"Just might be the way to survive the sun spot lull." ? as Ed says!

I thought I read something about this recently, but I can't find the thread in the Elecraft nabble archives.

Frequently when I power-on my KX2, the internal speaker is dead. To get it working again, I remove the internal battery, jiggle the speaker wires, replace the internal battery and back of the rig, power it up, and the speaker works again. I can't see any worn spots in the insulation of the speaker wire.

What should I check next?

Has anyone built the resonator with a straight length of tube? Perhaps terminated with a 45 deg. cut? 
Might be an interesting experiment. 

The 45 deg long radius street elbow in 2" is an order only item in my area so thought I'd substitute a straight length.

Has anyone built the resonator with a straight length of tube? Perhaps terminated with a 45 deg. cut? 
Might be an interesting experiment. 

The 45 deg long radius street elbow in 2" is an order only item in my area so thought I'd substitute a straight length.

KD1JV has this version on his web page.
I built one several years ago from fibre board and cement.
Works very good and still using it,

Maybe this is the science behind the old trick of putting your 
headphones on the desk facing upward to copy weak signals in noise.  
I've never really understood the reason except that high frequencies 
[noise] tend to be very directional from a transducer and dissipate 
rapidly, while lower frequencies are not directional.  At any rate, I 
know it works.

During my adventures in SE Asia long ago, we used turbine generators.  
They were 400 Hz, ran on JP4, and were light [two troops could easily 
carry them], but also important, their noise was very high pitched and 
could be muffled easily with a few sandbags.  The LF rumble of a 10 KVA 
trailer-mounted MB-5 diesel generator [~1,500 kg] couldn't be muffled at 
all.

Yes. A number of the early designs in QST (decades ago) were straight
sections. 

If you want to play around with the tube, pick up a couple of long "mailing
tubes". They are cardboard, so not quite as acoustically efficient I
suspect, but easy to trim and fiddle with to determine what length you want
to make out of harder material.

Try Pipe organ design. ?Gives ?you the input to cut the tube to any audio frequency.

There was a commercial version available about 20 years ago and I used it
for quite some time. really made CW signals pop out of the background. May
build a new one of here.

Message-ID: <CA+h_a7KfG_=ZC7b9_qm7wwZ2vKL_X0o+YKvWBhYONk8z4TaVaw@mail.gmail.com>

Hello

after many year with paddles connected to SO2R and WKUSB boxes, now I want
to setup a second station for the contest.

All is OK with N1MM sending messages stores in function keys, but I
couldn?t get working the paddles connected directly to KEY in the back of K3

No send dits, and dots are very slow and dont vary if I increase SPEED in
the K3

Any suggestions to check in MENU or CONFIG?

thanks!

Message-ID: <1487361834259-7627057.post@n2.nabble.com>

Was looking for a vfo knob with finger dimple and found the beta Gem Products
knob which contains a dimple and a pimple.  It was pretty good but is a beta
that was printed.  I really liked the pimple better than the dimple and so I
made my own.  Simply took a black sheet rock screw and cut the head off with
a dremel and put a dab of goop on the bottom and stuck it on the knob. 
Works great, very easy to do and easy to remove as good should not damage
the knob. <http://elecraft.365791.n2.nabble.com/file/n7627057/knob.jpg> 

Tried to insert image not sure if that works here...

Hi, Jorge,

The Key jack is for a hand key, bug, or a binary keyed stream from the
logging program/WinKey box/etc.

Paddles directly to the K3 internal keyer need to be connected to the
"PADDLE" jack and the only way to affect the speed of the K3 internal keyer
is the speed control on the front panel of the K3.

I found a large O-ring, black rubber, stretched it out with pliers several times until I could simply slip it over the VFO knob and back from the edge perhaps a sixteenth of an inch or so all the way around. It looks good, blends in with the rig, and by placing a fingertip anywhere around the circumference of the knob with a bit of my finger resting on the O-ring, it tunes very easily. It's as good as a dimple or a pimple, it's cheap, it's easy, there's no glue or solder involved and the O-ring should slip off easily if I ever decide to try something else. So far, it works well enough that I haven't even been tempted to search for any alternatives.

Try this. Reported a bug almost 2 years ago. When the charger is operating in the KX3 and the alarm has also been set then the alarm never goes off and the radio will not turn on.

This bug is repeatable and has been confirmed by Elecraft.

However, it?s still not fixed after 2 years?not exactly attended to promptly is it.

The wavelength and frequency of musical notes can be found here:
    http://www.phy.mtu.edu/~suits/notefreqs.html

A closed end pipe as used in the resonant speaker is a half-wave
(half the given dimension).

Note also there will be some "end effect" because the sound continues
to vibrate past the end of the pipe - which means the pipe will need
to be somewhat shorter than the true half wave.  End effect is
generally about 20% of the pipe diameter (from reading up on pipe
design).  I don't know what the effect of a 45 degree "end" would be
but I suspect you would want to make the mid-point of the cut about
where a square end would normally fall.

One could also experiment with *closed end* pipes ... pipes with the
far end plugged and a notch or hole near the speaker.  Closed end
pipes are a quarter wave long which would significantly reduce the
size for those using low frequency tones.  An open 700 Hz pipe is
49.5 cm (without end correction) - an open 440 Hz pipe would be 78.5 cm
and a open 300 Hz pipe would be about 115 cm (nearly four feet!) long.
Unfortunately, I have not seen any information on the sound port
(notch) design for closed end pipes - or whether they can be driven
by a speaker.

I have not but you certainly can do it. The length of the tube will determine the peak resonant frequency and you would have to experiment with the length to tune it to the pitch you like best to listen to. 
Remember the days you would blow across a bottle to make a tone? The more you drank out of the bottle the lower the pitch. 
I like this project and I am going to build one and it will be with a straight tube mounted on a little stand so it aims towards me.

In the late 70's, I used a Sky Tec CW-1 resonant speaker.? $9.95 USD in 1977. ? It worked very well and had a very sweet sound.? A sleeve in the top allowed pitch adjustment.? I still have it, somewhere around here...

When I first got my KX3, I considered duplicating it (it is made primarily out of PVC pipe) so I could use two of them to take advantage the KX3's audio special effects.? So many projects, so little time.

Message-ID: <1487372211682-7627071.post@n2.nabble.com>

Hi all

My CAT control has stopped working and I hope someone can help. Sequence of
events is as follows - 

Fitted KIO2 and made CAT cable - this worked

Bought XV-50 and extended cable - this worked

Bought XV-144 and extended cable further - this worked

Entered offset frequency for XV-144 - CAT stopped working

The K2 still controls the transverters OK but my computer won't talk to the
K2.

Checked connections in all RS-232 plugs - all fine. 

Tried three different computers and several different programs (DM780,
WSJT-X, fldigi etc.) - none of these work. 

Tried different COM port (know to be a working port).

Removed KIO2 and re-made several solder joints that looked suspect.

Still no joy. I have also noticed that my CW side-tone has disappeard.

Any thoughts?

Many thanks, Pete MW0RSS

I think a pipe with a speaker in the end is considered a closed end cylinder, but I am not completely sure.? If so, resonant lengths are shorter.? Here is the page from one of my favorite websites if you are interested in experimenting with resonant speakers:

Good educational website from Georgia State University.

Pete,

First, the wire connections to the transverters is quite separate from 
the TXD and RXD communications to the PC.

However, your loss of sidetone and the loss of connection to the PC are 
related.
You have firmware that is less than the 2.04r level (likely 2.04P) which 
allows you to change the sidetone source - that was in place to support 
older K2s.

Go to the K2 menu and select STL - set it for a level that will allow 
you to hear the sidetone with no difficulty - I recommend 40.
Then tap DISPLAY which will toggle the sidetone source.  When you hear 
sidetone, exit the menu by tapping MENU twice.  The sidetone source must 
be U8-4.

You should then have both sidetone and communications with the PC.

73,
Don W3FPR

A cylinder with a closed end is a "closed cylinder" and requires the 
formula that uses 2f instead of f.


The "real" formula accounts for lots of variables, including diameter of 
the sphere. But a ballpark formula that works just fine for less complex 
designs is just Length (in feet or fractions of a foot) equals the speed 
of sound in air (in feet per second which is approximately 1100) divided 
by either f (for an open end cylinder) or 2f (for a closed end cylinder) 
where f is the desired frequency of resonance you want. ?Much like 
making a simple dipole, you can start with the formula but it takes 
trimming to get it optimized.


Example: ?You want a speaker resonant at 600 Hz. ?It is closed at one 
end ( the end in which you mount the speaker). ?The tube is *about* two 
inches in diameter. ?L=1100/2f ?-- L=1100/1200 ?-- ?L=..916 ft. ?-- 
?.916 inches x 12 inches = 10.9 inches. ?


The preceding is not perfect but, like a dipole, it needs final 
trimming. ?That's where an adjustable design (like the PVC versions with 
a sleeve) make it easier to trim vs. building a wooden box (like the 
KD1JV box design).

I'm throwing out an unsolicited and not so shameless plug for Tom and
Win4K3Suite.  If you look at the eham reviews, you will see that I wrote up
a verbose review and gave Win4K3Suite a 5.  For sharing the CAT interface
on your K3/K3s, I'm not aware of anything better and as stated in the eham
review, it's worth the price just for the CAT interface sharing via com0com.

For years I have been an NaP3 and LP-PAN2 / LP-BRIDGE (CAT sharing) user.
While LP-BRIDGE works pretty well, NaP3 as always been a mixed bag where it
just hasn't been rock solid over time... in my opinion anyway.  Waiting for
LP-BRIDGE to create it's virtual serial ports is a minor nit-pick, but
Win4K3Suite and com0com have been a very rock solid / reliable solution for
me since November of last year and there is no wait for virtual com port
creation at boot time or when you start up Win4K3Suite.

As I mention in the review, I was a tough sell at first and really didn't
give it a chance.  However, I bought an SDRPlay to tinker around with on
the side and so I revisited Win4K3Suite.  Once the light turned on around
the K3/K3s CAT sharing capabilities and I took some more time to use the
band scope in Win4K3Suite, I was sold.  The feature set on the band scope
isn't as robust as NaP3, however I have grown to prefer the simplicity of
Tom's band scope implementation.  And the huge plus for Win4K3Suite is the
active support and feature updates.

I have returned to using LP-PAN2 as my pan adapter with Win4K3Suite.  The
SDRPlay is an interesting one cable solution, but the receiver and blocking
dynamic range that the SDRPlay has is not even in the same league as the
LP-PAN2 and a good 192khz sound card (not in the same universe for that
matter).  I haven't tried the new SDRPlay RSP2, but it may be worth a
look.  If you are a contester and don't want to watch a pumping spectrum
display with strong signals anywhere in the view, then I would recommend
staying away from the SDRPlay RSP1.

If you have wanted to trying something else out there for CAT interface
sharing with your K3/K3S (and other K line transceivers), you should give
the Win4K3Suite a try with the 30 day demo.  Tom has been very responsive
to resolving issues in my experience and also very responsive to questions
etc... also, if you want a solid spectrum scope / pan adapter solution that
just works and requires no baby sitting and tweaking, you should give it a
try.  The irony here is that I haven't even touched on the full graphical
interface Win4K3Suite exposes to control the Elecraft radios.

End of the unsolicited plug for Win4K3Suite... oh, one more thing, the new
3D spectrum display looks like a really cool piece of eye candy and the
remote power tool will be another nice addition.

I was at a Red Cross headquarters working ECOM when the room filled with 
bystanders.  All of the power supplies were facing the operators while 
their exposed backs were next to the crowd.  I noticed a lot of hand 
jewelry.  I got the most important looking person's attention and 
mentioned how a dead short across 40 amps would effect his hand.  Since 
I had only been there a few minutes he looked at me funny and then at 
the exposed wiring.  Soon afterward there was someone covering them with 
tape.  High amperage DC is very dangerous.  You would need to have a 
finger or hand amputated if your jewelry shorts it out.

	rev. 5.57:  Faster response to high reflected power
Message-ID: <DFDD9C73-F60B-426D-ABB4-7A279A25FC11@elecraft.com>

Hi all,

K3/K3S beta firmware rev. 5.57 is now available on our K3 software page. This release has enhanced protection from transient events that cause high reflected power, such as antenna or feed-line opens or shorts. 

(Winter seems to be the season for such things, with high winds agitating intermittent antenna systems. In our own [brutal] testing, we set power to maximum, tuned into various loads, then applied dead shorts and opens repeatedly. No damage observed on any test unit.)

See release notes below for additional details. 

For instructions on installing beta releases, refer to our K3 software page. (Beta releases are not automatically recognized by K3 Utility.)

MCU 5.57 / DSP 2.88 / FPF 1.26, 2-16-2017
 
* FASTER RESPONSE TO HIGH REFLECTED POWER: The transceiver will now reduce drive much more quickly when transient conditions cause excessive reflected power. This roll-back in response does not change the set power level (PWR knob); instead, it temporarily reduces drive to get below the reflected power limit. This means that once a better match is restored, such as when using an antenna tuner, the set power level will automatically be restored.

In the late 70's, I used a Sky Tec CW-1 resonant speaker.  $9.95 USD in 1977.   It worked very well and had a very sweet sound.  A sleeve in the top allowed pitch adjustment.  I still have it, somewhere around here...

When I first got my KX3, I considered duplicating it (it is made primarily out of PVC pipe) so I could use two of them to take advantage the KX3's audio special effects.  So many projects, so little time.

Hi all,

Beta firmware rev. 2.70 is now available on our KX3 software page. See release notes below for details.

MCU 2.70 / DSP 1.49, 2-17-2017

* AM TX BANDWIDTH INCREASED: The AM transmit bandwidth is now approximately 100-4000 Hz (was 100-3000). TX EQ can be used to further shape the passband.

* AM TX ALC IMPROVEMENTS: Fixed a bug in the AM power-control algorithm that was causing power output to start too high, then decrease over time when the operator is speaking. In addition, peak power output is now displayed, rather than power/4 (25%). This is intended to make the operator aware of the actual output from the radio, which accounts for the observed current drain, stress on dummy loads or antennas, etc.

* SCANNING WORKS WITH FREQUENCIES BELOW 1.0 MHz. Previously, scanning would stall in this case.

For software developers:

* DT, FR, and FT HOST COMMANDS DISALLOWED IN TX MODE: Previously, these commands (data submode, unsplit, and split) could be sent to the K3 during transmit from software applications. This could sometimes cause side effects such as muting of transmit audio in DATA modes.

* RIT CLEAR SWITCH UPDATES RIT OFFSET AT PX3 PANADAPTER.

* POWER-OUTPUT CONTROL COMMAND (?PC?) FIXED: The PC command now correctly handles the KX3?s power ranges (up to 12 W or 15 W depending on band).

* PSK31/PSK63 SELECTION (ETC.) VIA REMOTE COMMAND: When the DATA submode is being modified under remote control, a software application can now select between PSK31/PSK63 using the UP/DN control commands. Similarly, UPB/DNB can be used to select the desired TEXT decode mode (DEC OFF, TX ONLY, RX THRn). To determine the current state of any of these parameters, use the DS or DB commands. Refer to the Programmer?s Reference.

A cylinder with a speaker in one end and open in the other is an "open"
cylinder (open pipe).  It is a *half wave* in air which means the
formula uses 2f instead of f.

A "closed cylinder" is excited on one end and the other end is closed
(plugged).  A closed cylinder is a *quarter wave* in air - its formula
would use 4f instead of f.

microKEYER II interfaces to both the K3 and the K3S the same way.

With the K3S one uses the Elecraft supplied E98027 cable between the
RS232/P3 (RJ-45) jack and the XCVR jack of the P3 *as shown on page*
*19 of the K3S Owners Manual*.  The RS-232 plug from the DB37-EL-K3R
or DB37-EL-K23 cable connects to the PC jack of the P3.  If you do
not have the P3, connect the RS-232 plug from the microHAM cable to
the DE9 connector of the Elecraft supplied E98027 cable.

*DO NOT USE* the Elecraft CBLP3Y cable and USB connection on the K3S.

The +13.8V (power) plug connects to the "switched 12V" output of the
K3/K3S (and the DB37PWR jumper in MK II is set to power from the cable
instead of the +13V jack - per the microHAM Users Manual).  Line
In/Line Out, ACC, PTT, Mic and Key plugs attach to the matching jacks
on the K3/K3S.  Note: the K3S should be configured for RS-232 and
*not* USB as documented in the Elecraft K3S Owners Manual.

Now, could you provide extended TX audio bandwidth on the K3/K3S also?  It would be good to have it as a proper ?feature" .. :-)

Subject: [Elecraft] Quick Way To Accurately Measure K3s CW Filter Offset?
Message-ID: <06ac01d289c1$4e879ed0$eb96dc70$@ad6a.com>

Hi Folks,

 

I'm having a go at my first CW contest for many years (and boy, am I
rusty!!).

I've worked several new countries already, BUT, I noticed my K3s main and
sub receivers' 400Hz and 200Hz CW filter offsets are all quite a bit off
(even though I put the offsets in that were written on the filters), causing
me to tune the stations in at a lower than optimal tone (in order to hear
them properly) and trying to put in an XIT offset so they can hear me in
their tight RX passband. So far, it's not working that well. At a rough
guess, I'd say they were about 200 to 300Hz low of where I need them to be
(600Hz tone is my chosen optimal listening frequency).

 

So, my question is, is there a simple way to accurately determine what the
frequency offset of each filter is without having to open the rig up and
dive in with test equipment?

 

I'm guessing it could be something like:

a.	Tune in a strong-ish CW station or carrier to exactly 600Hz audio
(use the tone mon to compare with the 600Hz reference audibly)
b.	Note the VFO frequency (on FINE)
c.	Use the RIT function to tune the station/carrier in to the peak of
the crystal filter
d.	Note the offset
e.	Apply the offset to the crystal filter bank

 

What do you think of this procedure?

Got a better/quicker one?

Any/all input most gratefully accepted.

 

Cheers es 73,

Dave AD6A

The confusion here is a common one, closed vs open ended resonators, especially if one looks at the poorly explained graphs in most physics texts.

The speaker, attached to one end of the pipe, is not the closed end, it is open, since it drives the air particles at that end, and that makes it a displacement antinode, where the particle displacement is maximum.

Hi
    I was wondering if there is a problem using the A/B switch   on the SP3
as a  on / off   switch for audio from the k3.  The k3 would be on.
It seems like this would be ok but I am checking with the experts here.

Richard,

If your K3 has all the audio amplifier mods installed, there should be 
no problem.  If you have an early K3 without those mods, you could 
damage the speaker audio amplifier by driving it into an open or shorted 
load.  Yes, the A/B switch will make the load to the K3 an open circuit 
when switched to the non-K3 position.

See the listing of K3 mods to determine whether your K3 has the mods 
installed when you bought it or if they should be added.

Adding the mods is not difficult and can prevent a trip to Elecraft for 
your K3 should the audio amp fail.

73,
Don W3FPR

Hi,

Why would the amplifier be damaged from driving an open circuit?
Transformerless solid state audio amplifiers typically are perfectly happy
driving an open circuit.

Subject: [Elecraft] K3 very bassy XMIT audio (weird problem)
Message-ID: <1487447220341-7627101.post@n2.nabble.com>

I?m setting up a new K3s and having a very weird problem with the XMIT audio
adjustment. The problem exists on both electret (IC Proset) AND a Heil
dynamic mike. I properly set and adjusted bias (on or off), preamp (on and
off) and low-high settings in the MENU depending on the mike in use.

As soon as I speak and generate audio, the monitored audio sounds VERY
bassy. But the instant I readjust either the MIC GAIN or CMP pots even ever
so slightly (just nudge them) while speaking, the audio instantly reverts to
normal crisp audio and sounds fine and remains that way until and unless I
unkey. Then it reverts.

I see (hear) this ONLY when monitoring my audio while setting up. If I
record myself using the DVR, changing the MIC/CMP controls mid-transmission
does NOT affect the audio characteristics and it sounds quite bassy on
playback.

And I did try to adjust the TX equalizer levels to no avail.

Anyone experience this or have any ideas?

Tnx,

ED

Dick,

I think all is well, as long as the TX Gain Calibration succeeded.
What you are seeing in the summary is the gain factor for each band.
The RF Gain is not constant from one band to another, but after a 
successful calibration routine, those values are used by the firmware to 
compute the amount of drive needed to achieve whatever power output you 
requested with the power knob.

Don W3FPR

Message-ID: <1487453449762-7627105.post@n2.nabble.com>

Hi all,

Just a quick note to let all interested to know there is a new version of
the free QRPworks ADIF Utility available (version 1.9).  The ADIF Utility is
used to export your log in any of the QRPworks products to an ADIF file on
your PC or Mac. 

The Utility was enhanced based on a request from a SOTA operator (Tnx, Art
HB9DCO) but is applicable to all operators, whether you climb a peak or not. 
The enhancement is to add additional fields to make the ADIF file more
compatible with existing ADIF to CSV file converters.

If you use a SideKar, Ham Central Terminal, or Key Log Go with your KX2,
KX3, K3 or K3S, this enhancement applies to you.  No change to the SideKar,
Ham Central Terminal, or Key Log Go firmware is required.  All of the
changes are in the ADIF Utility. 

It can be downloaded on the Support page at www.QRPworks.com.

73,

Shel KF0UR

I worked with a guy missing his ring finger after accidentally getting his
wedding band across the high-current supply bus and the airframe in an
aircraft console. The ring immediately welded to the current source so he
could not move his hand. He said that he passed out from the pain as the
metal melted into his flesh.

Others in the shop spoke of the guy who lost a hand to a metal watch band
the same way. 

I never work around a car battery or other low-voltage, high current supply
wearing jewelry. If you wear a wedding ring that you cannot or do not want
to take off, do what hospitals do and wrap a band-aid around your finger
covering it.

Subject: [Elecraft] K3 loss of rx sensitivity
Message-ID: <3d079d2e-0c1b-208c-3904-857e2938a7f6@telus.net>

I have a K3 serial # 025** with FW REVS 4.67.
With no changes I not an apparent reduction of rx signals.
Particularly the P3 waterfall is bright enough but barely
shows traces with S5 noise level.
MSK144 reports are always weaker to me than my tx to them.
I'm at a loss as to where to start and correct this.
Any help appreciated.
Thanks.

I worked with a guy missing his ring finger after accidentally getting his
wedding band across the high-current supply bus and the airframe in an
aircraft console. The ring immediately welded to the current source so he
could not move his hand. He said that he passed out from the pain as the
metal melted into his flesh.

Others in the shop spoke of the guy who lost a hand to a metal watch band
the same way. 

I never work around a car battery or other low-voltage, high current supply
wearing jewelry. If you wear a wedding ring that you cannot or do not want
to take off, do what hospitals do and wrap a band-aid around your finger
covering it.

Amen! I shorted my wedding ring and a wrench across a car battery once. It
burned out a small part of the ring, and left a blister that lasted a week.
I was lucky. I also got the ring off before the swelling made it impossible.
I was doubly lucky.

John,

If I understand you correctly, the P3 level also dropped.
That places the problem at the front end of the signal path - The T/R 
switch and the ATU.

But first check the external connections.  The PL-259 connector should 
be tight, and you need to check any coax jumpers that you have in the path.
What is the possibility that something has happened to your antenna - 
yes, it may still transmit without obvious problems, yet receive can be 
down.

With the current state of propagation, it may be that signals are just down.

Do you have a signal generator?  The Elecraft XG1, XG2 and especially 
the XG3 are excellent.  They will generate a -73dBm signal - which 
should show up as an S-9 signal if the preamp is on.

Do you get better reception if you connect the antenna to the RX antenna 
jack?  If so, the problem is in the K3 and you should contact K3support.

73,
Don W3FPR

After pain, visual learning is often the best teacher.  The rest of us 
sense wallet depletion.


Don't forget that some of the battery packs we commonly use now (LiFePo4 
is my example) are capable of tremendous current (mine are 'fused' by a 
BMS at 100 amps).

Another trick is to use a pair of cotton gloves with the

Stan,

Thanks for the video, most impressive.

I have one comment regarding the need for an amplifier with the KX1 /KX2 or KX3 radios, there is another YouTube video from a couple of years ago that appears to be almost what the more recent QST article is based upon and in it the constructor has it connected to a KX1 and it seems loud enough.

https://youtu.be/4iNELueaU6M

Then there is another video where another constructor dissects the original commercial design and makes one, this really shows how efficient the design is when at the end he compares the bare speaker on its own and how weak it sounds compared to when it resonates.

https://youtu.be/MF8bk6958Hg

The key seems to be that in both of the above cases the lower part of the resonant speaker is + not + sealed completely, air is allowed to enter and exit, though there is sound deadening material in the cavity. Perhaps that explains the greater sound efficiency?

This is something I plan to investigate myself with my KX3, once I get the parts here, of course being in the UK we are now metric and so some slight adjustments are necessary as our pipe is 50mm and so on. A friend has offered the services of his laser cutter and 3D printer which will come in handy too!

I was involved in product testing in my former career.
One large computing machine which I worked on had a backup battery 
consisting of 4 AA cells, which no-one thought would be a problem, but 
during environmental testing at shipping extremes, condensation formed 
and created leakage paths.  It was a hard sell to convince management 
and many engineers that AA cells could cause a problem.

The following action was to do extensive testing in the power systems 
lab in which several destructive tests were performed, which included 
shorting the battery pack terminals.

It is amazing how much current those "lowly" AA cells can produce in a 
shorted situation.  Under short conditions, they are just as powerful as 
any other battery, but the duration of the huge current discharge is 
shorter than for larger batteries.

Lesson I learned is to be careful with any battery.  High density 
battery chemistries make the short circuit discharge duration longer and 
can cause more damage.

Following along with James' question, should the K3 be double boxed for 
shipment back to Elecraft for the "migration?"

Jim,

I don't know if you can get the box and spacers that Elecraft uses - you 
can give them a call and ask.  They use a box and dense foam supports 
which fit the K3.  After your K3's first trip to Elecraft, you will have 
a box like that when it returns.

I ship a lot of radios (K1, KX1, K2 and XV series transverters), so I 
have come to know what packing methods will work well and protect your K3.

The requirement for safe shipping (by all carriers I know of) is that 
you have 2 inches of protection space on all sides between the radio and 
the box.
The very most important aspect is that the radio cannot move in the box 
if the box is subjected to a sudden stop at the end of a sorting ramp.

The K2 will meet those requirements by using a 16x16x8 box.  Wrap the K3 
in bubblewrap (using only a minimum amount of tape, it does not have to 
be wrapped as a mummy), then put almost 2 inches of packing peanuts in 
the bottom of the box.  put the K2 in and fill the rest of the box with 
packing peanuts.  The bubblewrap is to keep the packing peanuts from 
sticking to the K3.

If you do not have packing peanuts, put layers of bubblewrap to 2 inches 
thick under the K3 and use crumpled newspaper to fill the rest of the 
box.  If you use crumpled newspaper, make sure there is enough tightly 
packed at each of the K3 corners so the K3 cannot move in the box.

With an object as heavy as the K3, do not use the large air bags.  While 
they fill a lot of space, when pressure is applied, they can burst 
leaving little protection.

You can always take your K3 to a shipping depot and they will package it 
for you.  But they will usually wrap the radio "like a mummy" with lots 
of tape holding the bubblewrap - that gives the technician unwrapping it 
fits to get all the wrapping off.
But the shipping depots are responsible for the safe packing of whatever 
you are shipping.  Yes, they charge for that service.

Ron,

With proper packing as I indicated in my post a few minutes ago, there 
is not real need for double boxing.  The important thing is that the 
radio is not able to move in the box if subjected to an impact.

Rarely do I receive a damaged radio, and in all cases of damage 
(normally minor), the radio moved within the box.  Only rarely do I find 
a damaged box, and usually that is normal "wear and tear" from handling.

I have most experience with USPS and UPS although sometimes FedEX. 
Those carriers are good with packages, and as I said, only rarely do I 
find damage, and in all cases that was caused by movement of the radio 
in the box.

I have been shipping and receiving the Elecraft legacy gear since 2004, 
and have never had a claim that was worth pursuing.  It is easier to 
just replace the BNC connector that contacted the packing box than to go 
through the process of placing a claim.

Having done the change myself and helping the vendor make the customization
for the K2, I would have to recommend the Batteryspace item CU-J1087-V1.

The "V1" connectorization allows for a drop-in incorporating the back panel
cutoff switch

There's a thread about all this from late August - early September 2015
that contains verbose detail regarding this topic.

With the hindsight of a year and a half plus experience, I'm even more

James,

I expect Elecraft could sell / send you the proper box for your K3.  The
cost to mail an (assembled) empty carton shouldn't be too high, and sent
via Priority Mail can be anywhere in the US within 2 - 3 days. This is
Rose's experience with her cases and covers business.

Hi James, It might be simpler if you are not comfortable packing & shipping gear to let the UPS or FedEx store pack and ship the radio. If they pack it ?in house? and there is any damage in shipping they will cover it 100% for whatever you claim its value to be. I normally pack myself but a couple years ago I sold an Alpha amp to a man half way across the country and let them pack it in 2 boxes as I didn?t have the original boxes. I?m guessing Elecraft will ship the radio back in a proper K3 factory box.

James

I had to send my KPA500 (including transformer) back to Elecraft from NY.  My KPA500 was a kit so, like you, I had to figure out the best packaging.  The KPA500 is much heavier than the K3s, so if you package as has been recommended (i.e. 2 inches peanuts or bubble pack on all sides and no movement), you should be fine.  And, be sure to get the correct amount of insurance.  By the way, the packaging sent back from Elecraft had absolutely no peanuts or bubble wrap; it wasn?t needed.  The two big foam end pieces held the KPA500 rock solid in the box;  There?s no way I?m throwing that box and foam pieces away.

Good luck,

Joe

Having done the change myself and helping the vendor make the customization for the K2, I would have to recommend the Batteryspace item CU-J1087-V1.

The "V1" connectorization allows for a drop-in incorporating the back panel cutoff switch

There's a thread about all this from late August - early September 2015 that contains verbose detail regarding this topic.

With the hindsight of a year and a half plus experience, I'm even more happy with this setup now than I was then.? I do use their 'matching' charging brick.

I frequently wonder just how much protection a typical SWR protection circuit
can provide against an instantaneous discontinuity if it relies totally on a
feedback approach. If the response time of the feedback circuit isn?t faster
than the risetime of the voltage at the output transistors that results from
a sudden failure, then it isn?t apparent to me how this approach can provide
reliable protection. A well-designed feedback circuit can provide adequate
protection during tune up into a high SWR. It can also provide adequate
protection during CW or voice modulation since the bandwidth, and therefore
the risetime, of the transmitted signal is limited by the transmitter
circuitry. However, the voltage rise due to a sudden failure in an antenna
or transmission line connection could conceivably result in a risetime in
the 100 nsec range at the drains/collectors of the output transistors. I
have never seen any specs on the response time of any SWR protection
circuit, but I would be surprised if any of them can even approach the low
nsec range. If the failure occurs when the transmitter is at full output,
then I would expect the voltage to quickly exceed the max rating on the
output transistors. This is clearly a worst-case scenario that probably
doesn?t occur very often. However, I wonder how many (if any) manufacturers
of ham transmitters have disconnected the antenna when their transmitter was
putting out full power as part of their evaluation of their SWR protection
circuit.

Download and install the latest K3 beta firmware.  The time to power 
reduction due to high SWR has been reduced substantially.

It has been a long time but... I had a battery in my pocket (not sure any
more but probably a 9v), no change in the pocket and do not remember what it
was that caused the problem (probably my knife) but something apparently
shorted the terminals and I felt uncomfortable, jostled my pocket, then
warm, then hot and HAD to get whatever it was out.  I burned my hand. The
battery got MUCH hotter even after it was out.  It would have caused a
serious burn to my leg had I not removed it.  I could only describe the
situation as an avalanche failure inside the battery.

I will not forget that experience and never put batteries in my pocket of
where they can short any longer.

I was involved in product testing in my former career.
One large computing machine which I worked on had a backup battery
consisting of 4 AA cells, which no-one thought would be a problem, but
during environmental testing at shipping extremes, condensation formed and
created leakage paths.  It was a hard sell to convince management and many
engineers that AA cells could cause a problem.

The following action was to do extensive testing in the power systems lab in
which several destructive tests were performed, which included shorting the
battery pack terminals.

It is amazing how much current those "lowly" AA cells can produce in a
shorted situation.  Under short conditions, they are just as powerful as any
other battery, but the duration of the huge current discharge is shorter
than for larger batteries.

Lesson I learned is to be careful with any battery.  High density battery
chemistries make the short circuit discharge duration longer and can cause
more damage.

I'm wondering if all I need do is build a 12vdc injector and apply to
the coax feeding the loop?

The lead-acid K2 battery is heavy and can corrode when its life is over, and is ancient. ?I just removed my K2 battery, and when I use it portable I am going to power it with a tiny KX2 battery, or a bigger 4S2P pack.
When I built my K2, I didn't use the Elecraft trickle charger. ?I ran the battery out to a separate jack on the back panel, and plugged in a smart charger made for small SLA batteries. ?You could build a KX2 battery into the K2 and do the same thing, charging it with the Elecraft charger. ?
Just an idea.
Using an external battery pack might be easier, given the now monstrous size of the K2 compared to a battery pack or KX2. ?How far Elecraft have brought us in 20 years. Twenty years before the K2 was the HW-8.

Good Evening,
The calendar may not show it, the weather surely doesn't, but there are 
a few signs that spring is coming.  I heard a grouse drumming on 
Wednesday, I have no idea why.  Then last night a barred owl started up 
right outside my window.  Next will come the tiny insects the 
hummingbirds enjoy.

   A solar stream is causing a little more noise but signals have been 
better this week.  It's all a matter of S/N; can you get enough signal 
above the floor or are you just copying holes in the noise.  That's good 
for a call sign but not a chat.

Please join us tomorrow on:

    14050 kHz at 2300z Sunday (3 PM PST Sunday)
     7045 kHz at 0100z Monday (5 PM PST Sunday)

     73,

One other consideration,if using metal tools around high current 
sources (like batteries or power supplies): Shorting the terminals 
may cause rapid heating and result in explosions.  An exploding 
lead-acid battery can hit you with shrapnel and acid which can burn 
you, blind you, or cause death!

I built one once with a 2-1/2" (6.4 cm) diameter PVC tube. Unfortunately 
I don't remember the exact length, but it was about 7" (18 cm) long. I 
simply glued a 2-1/2" speaker to one end. It resonated at about 600 Hz.

At one point I placed a tightly fitting lid from a spray can over the 
back of the tube and the speaker. It became significantly louder.

My experimental 2 cents.

Back in the way-back when I was a young communications tech (still had
hair) working for AT&T in Wash DC, the long distance office I worked in had
a 10,000 ampere 12 volt DC supply which supplied entire floors of Western
Electric 310A and 311 vacuum tube filaments, plus other stuff. Was
motor-generators plus floating battery backup. Single cell low gravity lead
acid batteries, about 20x20 inches and 5 feet tall, four strings in
parallel.

The bus bar hook up leading out of the battery room to distribution panels
was four 1 inch thick, 4 inch tall solid bars in parallel for the positive
rail and the same for the negative rail. So the DC conductor was a pair of
"wires" that each had 16 square inches of copper cross section.

It was not insulated, and anyone working in there had to have all metal
jewelry, watches etc removed. Also all tools except for the tip had to be
wrapped in this gunky black cloth tape, two wraps deep. No exceptions, ever.

A contract employee was in there once, and went in there with a large
unwrapped wrench, working over the top of the bus bars. He dropped the
wrench across the plus and minus bars, which were separated by about six
inches, way more than enough to insulate for 12 volts.

Accounts said that there was a flash and both ends of the wrench vanished
into metallic vapor. The center portion dropped through the gap without
ever losing speed and bounced on the concrete floor. It was so hot it
burned leather gloves. The speculation was that the battery line could
easily have supplied a pulse of 30,000 or 40,000 amps. On one occasion I
saw the load ammeter go over 10,000 amps.

Dunno if the idiot that went in there with an unwrapped wrench got canned
or not, and don't know if he suffered eye injuries from the flash. Rumor
was that he immediately left the battery room and exited the building.

The amps that can be supplied by modern lithium batteries are so high that
it can destroy and even explode the battery.

All prior warnings of this sort in these threads are definitely
well-founded and probably understated if anything.

Thanks Joe.  I used a common TRS audio cable, cut off one end and spliced
the proper wires and ground to the appropriate wires on the cut off end of
an old strait  through DB9 cable and it all works perfectly connected to
the ALS-1306 Kenwood cable.  The hardest part was using a DMM to identify
the wires/pins on the DB9 cable since they had atypical color coding.

  Excellent news, Wayne!

  If only you could consider making the "Mic Btn" settings mode-dependent,
my life would be complete (or thereabouts). Right now this is the #1
setting I need to change all the time: when using the Mic on SSB I have to
enable "Ptt", and when switching to DATA to connect my audio card for
digital modes I need to set it to "Off" because the audio card jack I use
keys PTT... :)

At least with UPS, DO NOT USE NEWSPAPER. From their "Internal Packaging 
<https://www.ups.com/content/us/en/resources/ship/packaging/materials/insulation.html>" 
page:
---------------------
*Kraft Paper
*Kraft paper_(not newspaper or newsprint)__**_is wrapped and crumpled to 
fill empty space inside a package with light-to-medium weight, 
non-fragile items. When using kraft paper, tightly wad the paper and use 
at least two inches (5.08 cm) around and between the contents. Make sure 
that there are at least two inches (5.08 cm) of kraft paper on all six 
sides of the box.
-----------------------
...and, UPS does not sell "Insurance" but rather "Assurance". Not 
exactly sure what that means other than, if there is a claim and you 
have failed in any way to follow their packing specs, it doesn't matter 
how much you declared or how much you paid for "assurance", you are S.O.L.

FedEx may be the same way but I don't know.

...just an FYI.

I thought the QRQ timing issues were fixed with the new K3 synthesizer.  
QRQ mode went to off when RIT was on because the synthesizer couldn't 
settle fast enough.  That may still be true regardless of synthesizer.

Do you have the new synthesizers? The CW qrq timing issues were greatly
improved with the new syns. That was matter of less time for the syns to
settle.

There is also a regular and fast qrq.

I make my own shipping boxes. I describe my procedure below which in reality
is much easier and faster than it reads. I have employed this to ship by
post office quite a few radios and power supplies (i.e. Collins and Drake
gear) and have not had any damage. I have found the Styrofoam used here to
be very 'forgiving'.

You need to 'float' the item in a single shipping box. Select a box that is
at least 2" wider on each side, top and bottom and 3-4" wider front and
back. Get some solid Styrofoam insulation, preferably 2" thick; 1" thick
will work. Make a template of the rig's front or back for size. Measure the
inside of the box's front and back for height and width. With this
measurement cut two pieces of the Styrofoam board using utility knife.
Center the template from above on the Styrofoam board, mark and cut out the
opening. Slide the two Styrofoam boards onto the rig, say 1", one front and
one back. You may have to partially notch the board to accept the rigs feet.
It should be a firm fit. Place the rig into the box. It should be a firm fit
and the two Styrofoam board supports will 'float' the rig in the box.

The Styrofoam board support boards and rig need to be secured in place. Once
the rig is floating in the box, it will become obvious where additional
blocking needs to take place. Take other pieces of Styrofoam, cut to size to
go between the rigs front (2) and back (2), glued to the box, and resting on
the outside edges of the rig away from any knobs. This will prevent the rig
from sliding forward or rearward. Now take other pieces of Styrofoam, cut to
size and glue inside to the box sides (3 per side) to hold the Styrofoam
board supporting the rig in place. You can add bubble wrap, crumbled paper,
peanuts, foam to fill the openings, front, back, sides, top and bottom. I
also try to place the rig inside a plastic bag to reduce any chances of
scratching.

I had to send my KPA500 (including transformer) back to Elecraft from NY.
My KPA500 was a kit so, like you, I had to figure out the best packaging.
The KPA500 is much heavier than the K3s, so if you package as has been
recommended (i.e. 2 inches peanuts or bubble pack on all sides and no
movement), you should be fine.  And, be sure to get the correct amount of
insurance.  By the way, the packaging sent back from Elecraft had absolutely
no peanuts or bubble wrap; it wasn't needed.  The two big foam end pieces
held the KPA500 rock solid in the box;  There's no way I'm throwing that box
and foam pieces away.

Good luck,

Before I take this up with the UK agent for Elecraft, I am curious as to
whether anyone else has experienced the yellow lettering rubbing off,
particularly at the bottom of the front panel?  I have only had my KX2 for
a couple of weeks and just had my first QSOs with it yesterday, so it's not
had any prolonged treatment.  It looks to me as if the lettering at the top
of the panel is fine.  White lettering seems much more robust.

	KX3)
Message-ID: <5AE055E1-E5BD-47F3-80DE-6011F07C0EDE@elecraft.com>

Hi all,

Today I was operating pedestrian mobile in the ARRL DX contest with just the MFJ1820T 20 meter whip. This 4 foot-long whip is very narrow banded, which isn't a problem over the full 20 meter band as long as you have an ATU available - the KXAT2 in the case of today's KX2 excursion. (Note: You also need a ground counterpoise. 13 feet is about the right length.)

When trying to use this whip on other bands, in a pinch, it can be tough on the ATU, given the sharp resonance of the antenna. But I realized I hadn't tried shortening the telescoping part when operating on frequencies above the target band.

It turns out that, at least in my case, the ATU could match to 1:1 on 17 meters by collapsing 2 lower sections. On 15 meters, I could get a 1:1 match by collapsing 5 lower sections. 

While this is certainly a compromise in terms of radiation efficiency, it does make the transmitter happy, allowing the use of full power. I didn't do any far-field tests to compare the shortened whip at 1:1 to the full length of the whip at much higher SWR, but for receive purposes, it was about a wash. 

As a bonus, there's less metal waving around in the air. This can be handy when you're walking, especially in a residential area with a lot of "Neighborhood Watch" signs proudly displayed :)

Hi Stephen,

We use epoxy ink for panel labeling, which is normally very robust. Our UK dealer should give you a replacement right away. If possible, we'd like to get the panel back for QA analysis.

Subject: [Elecraft] Slow output/no output on KPA500 after changing drive
	from K3
Message-ID: <1487540945967-7627146.post@n2.nabble.com>

Recently I've begun having a very annoying power problem with my K3/KPA500
combo on 40M.  I recently built a 7-foot diameter STL that I am using as my
sole antenna for that band.  

The problem started after I had some hard faults at QRO;  I gradually
increased the drive to full output but due to my closely mounting the loop's
capacitor and element ends (high voltage points) to its wood support stand I
might have had some arc-over; the previously perfect 1:1 SWR climbed into
the red and the amp would alarm.

I quickly corrected the mounting so that there was more distance between the
stand and high-voltage bits and was then able to load the antenna with
500-600 watts without fault thereafter.  That apparently corrected the
SWR/excessive dissipation issue entirely, except I am still left with
another issue.

*The problem is that whenever I key up and or change the drive level via my
K3's drive knob the amp's output either woks as intended or not at
all---especially beyond the 12-watt level. * Or if I have the drive set at
20 watts and up it to 22 or 25 or anywhere else the amp's output falls or is
nil.  SWR is still fine, 1.2:1 or better but that makes no difference
whatsoever in the amp's erratic behavior.

I have developed a sort of workaround method in order to chase DX with my
newly constructed loop using 400-500 watts SSB:

I hit the TUNE button on the K3 for a moment then immediately key the mic
and begin calling---that seems to "goose" the amp into transmitting for a
while.  If I don't keep transmitting often then it falls back into the "no
output" scenario and I must repeat the TUNE "fix" again to reactivate
things.

This has been happening both before and after I updated the firmware in the
K3 and the KPA500 the other day.  The updates installed without a hitch,
too.

I am sure that the TX Inhibit is OFF and most if not all of the other
parameters that could affect this are set to default.

I had the same problem with the power not coming out of the amp back in
November of 2011 but that turned out to be my using both the KPA to KE big
cable as well as a separate PA keying cable plugged in which shouldn't have
been---now there's only the big K3 multi-pin cable hooked up to the amp.

My HV reading is around 75 to 76VDC and it drops to 61VDC in the worst-case
scenario (generally about 63VDC or higher key down).

In searching this forum as well as Google before posting this today I ran
across a few similar situations posted by others---NOT ONE OF THEM COUGHED
UP AN ACTUAL DEFINITIVE SOLUTION to this strange anomaly.  IIRC, Don, W3FPR
did say that the problem was in the K3 and not the amp and I tend to agree. 
This often happens when I change the drive setting ever so slightly.

Others had cabling issues that were corrected and as I discovered to my
dismay that the majority of folks chalked up the issue to an occasional
glitch that was of little consequence.

Not to me!   I would LOVE to be able to fix this once and for all and be
confident that when I key the mic or trip my VOX that my call is being sent
at the power level desired.

I have also heard that this may be a transformer issue or a voltage tap
issue; any thoughts or info on these would also be welcome.   I sure hope I
can get this sorted before the ARRL Phone contest in a couple weeks!

Thanks for any help that comes my way; I really hope I won't need to ship
this gear to Elecraft for diagnosis/repair if I don't absolutely have to.

I can no longer easily open/read the mailing list sent to my Outlook inbox
(problem with a recent change in Outlook, I think) so feel free to email me
directly as well as reply to the list:  cathrowinternational (at) hot mail

Hello

is possible to decrease only the speaker volumen level and no affect the
phones level?

We use to have SPKR+PH ON so the people at the shack can hear how is going
the contest.

But when the Operator adjust AF comfortable for the phones, the speaker is
very high affecting also the operator that is using phones but can hear the
excessive high level of the speaker

thanks,

I got my KX2 on Thursday (It fills out a pretty big Elecraft "stable"). I got on the ARRL CW DX contest with a dipole and 2 element beam at 25'. I was able to work all continents on 10watts. Europe was the most difficult. I worked a bunch of JA's on 40 at night.? I ended up using one of my Begali paddles with the rig. (I think it weighs more than the radio!) The interface with N1MM was simple and works very well. The receiver is very strong and only got clicks from stations a? hundred hz away. 
?? Here's what I liked the most. The filter and NB buttons are next to the volume and selectivity knob. And on the left side.? (Probably because I am a leftie) I like the band switch. The peg is perfect? The radio barely got warm all day/night. I tried driving my Ameritron 1306 with it and got 300w output. It helped on a few contacts. Very happy with the radio. Way to go E'craft!
???? I like the suggestion of the MFJ whip on 20. Is it better than the Maldol?

Jorge,

One method I can think of is to use an external speaker with a variable 
resistor in series.
The other way is to use amplified (computer) speakers which can usually 
be turned down in volume.
The 3rd alternative is to use more sensitive headphones.

If you enjoy mixing astronomical sightings and amateur radio you could 
try timing occultations or the total solar eclipse coming this August.  
Stay in touch with the other folks along your path of occultation and 
find which of you caught the best graze angle. Timing a bright star is 
easily done without a telescope.

Would someone share the dimensions of assembled K3/s box as it comes from factory???? Am guessing it comes with surround Styrofoam?

You need to 'float' the item in a single shipping box. Select a box that is
at least 2" wider on each side, top and bottom and 3-4" wider front and
back. Get some solid Styrofoam insulation, preferably 2" thick; 1" thick
will work. Make a template of the rig's front or back for size. Measure the
inside of the box's front and back for height and width. With this
measurement cut two pieces of the Styrofoam board using utility knife.
Center the template from above on the Styrofoam board, mark and cut out the
opening. Slide the two Styrofoam boards onto the rig, say 1", one front and
one back. You may have to partially notch the board to accept the rigs feet.
It should be a firm fit. Place the rig into the box. It should be a firm fit
and the two Styrofoam board supports will 'float' the rig in the box.

The Styrofoam board support boards and rig need to be secured in place. Once
the rig is floating in the box, it will become obvious where additional
blocking needs to take place. Take other pieces of Styrofoam, cut to size to
go between the rigs front (2) and back (2), glued to the box, and resting on
the outside edges of the rig away from any knobs. This will prevent the rig
from sliding forward or rearward. Now take other pieces of Styrofoam, cut to
size and glue inside to the box sides (3 per side) to hold the Styrofoam
board supporting the rig in place. You can add bubble wrap, crumbled paper,
peanuts, foam to fill the openings, front, back, sides, top and bottom. I
also try to place the rig inside a plastic bag to reduce any chances of
scratching.

I had to send my KPA500 (including transformer) back to Elecraft from NY.
My KPA500 was a kit so, like you, I had to figure out the best packaging.
The KPA500 is much heavier than the K3s, so if you package as has been
recommended (i.e. 2 inches peanuts or bubble pack on all sides and no
movement), you should be fine.? And, be sure to get the correct amount of
insurance.? By the way, the packaging sent back from Elecraft had absolutely
no peanuts or bubble wrap; it wasn't needed.? The two big foam end pieces
held the KPA500 rock solid in the box;? There's no way I'm throwing that box
and foam pieces away.

Good luck,

One way would be to use a separate amplifier and speaker connected to LINE-OUT. Then it would be independent of AF gain. 

TNX for the Qs!

The solution to that is to go into Windows (assuming that is what you are using) and shut off all internally generated sound.

I can run up to the K3 max of 100 wpm with no stutter, with the sound disabled.

Hi! I got the below advice which worked for me: For WSJT-X and the K3S use: Mode = DATA Data sub-mode = DATA A MENU:MIC SEL = Line IN Make sure nothing is plugged into the "LINE IN" jack. Set the PWR slider in WSJT-X to the top, click Tune and adjust the K3 MIC GAIN for *four bars* of ALC. Adjust the K3 PWR control for the desired power output. Best regards, Bret C.

	I am having the same problem, with not being able to send audio to my K3S from WSJT-X. The transmitter is being keyed, but nothing is showing up on the ALC. I normally use WSJT-X with HRD, but have tried to bypass HRD to see if the will work by going direct, which did not work either. It has been working fine until this morning when it quit working. I am able to send the audio to the K3S using DM780, running PSK31. 
I am running Windows 10 on a HP I5, 64 bit. The computer has two sound cards, one for digital and the other for YouTube, music and such. For digital I am setup in both HRD and WSJT-X, with the sound card settings &quot;Speaker USB Audio CODEC&quot;. A few days ago I was able to have my default sound card set to &quot;Speaker Envy24 Family Controller&quot;, but something happen and now the only way I was able to get the sound to the K3S was to change the default sound card to &quot;Speaker USB Audio CODEC&quot;.
However, I was able to work PSK on the HRD DM780 with the default sound card set to &quot;Speaker Envy24 Family Controller&quot;, but not with WSJT-X.
I did update my Firmware on my K3S this morning to 5.56, if I remember correctly the WSJT-X was working correctly after words.
Uninstalled the WSJT-X and reinstalled with no change in the problem. I have been operating WSJT-X now for about 2+ years, so I am not a newbie. However, I sure am pulling my hair now........

Hi Doug,

Congrats on your good showing in the contest. I worked several while walking and had a nice view from the top of the hill.

In my tests, the MFJ whip could handle a lot more power than the Maldol. The Maldol faded after 20 or 30 seconds at 10 watts, as indicated by the SWR steadily going up. A more scientific test would be a good idea. But I don't think the Maldol HF whips are available anyway, so it's a mute point.

Activity for the Aug 21 total solar eclipse is developing. Interest in doing propagation studies to explore the effect of totality on radio wave propagation seems to be of particular interest. 
??? The activity I am going to do is to set up a station at center line and stimulate the reverse beacon network. The change in received level is easily recorded by the network. The eclipse is only 2.5min long, so there is not going to be much data. One might also want to monitor signals that ordinarily would propagate through the path of totality. 
?? I mention the efforts here because a KX2 and small antenna would not add to the eclipse baggage and may provide a source of data that could be interesting. 
?? Here is a link to some of the events during the eclipse. Others are easily found with a search of the internet. Feel free to contact me directly.? Doug

Wayne, my favorite go to band has been 17 meters.  I originally did Ped mobile with the FT817 and since there was no specific antenna, portable for that band at the time I used a Maldol AH-c14 with one length at the tip shortened dragging an 11' counterpoise.  It is what I now use for the KX2.  For the heck of it, I even tuned it on 40 with good success, didn't try working on 40 just found it interesting that it loaded at 1.2: with the fully extended whip and the 11' counterpoise.

Subject: [Elecraft] MFJ 20-meter whip on 17 and 15 meters with the KX2 (or KX3)

Hi all,

Today I was operating pedestrian mobile in the ARRL DX contest with just the MFJ1820T 20 meter whip. This 4 foot-long whip is very narrow banded, which isn't a problem over the full 20 meter band as long as you have an ATU available - the KXAT2 in the case of today's KX2 excursion. (Note: You also need a ground counterpoise. 13 feet is about the right length.)

When trying to use this whip on other bands, in a pinch, it can be tough on the ATU, given the sharp resonance of the antenna. But I realized I hadn't tried shortening the telescoping part when operating on frequencies above the target band.

It turns out that, at least in my case, the ATU could match to 1:1 on 17 meters by collapsing 2 lower sections. On 15 meters, I could get a 1:1 match by collapsing 5 lower sections. 

While this is certainly a compromise in terms of radiation efficiency, it does make the transmitter happy, allowing the use of full power. I didn't do any far-field tests to compare the shortened whip at 1:1 to the full length of the whip at much higher SWR, but for receive purposes, it was about a wash. 

As a bonus, there's less metal waving around in the air. This can be handy when you're walking, especially in a residential area with a lot of "Neighborhood Watch" signs proudly displayed :)

Ummm ... I guess it depends on exactly what you do.  I worked for a 
defense contractor for quite awhile, "When you were done with it ... 
shred it."  One young fellow still had his dog tags on the chain around 
his neck.  Fortunately they gagged the shredder before the chain 
strangled him.

My KX2 arrived with the lower third of the left side downstroke of the M 
in the MENU label missing. I have been using the KX2 for antenna testing 
in my backyard and have not noticed any degradation of other labels. I 
suspect this is a case of a label that just wasn't screened completely

Message-ID: <1487595619822-7627175.post@n2.nabble.com>

I operated my K3/100 remotely this weekend in ARRL DX.  I noticed the top of
the case getting pretty warm - not too hot to touch, but warm enough I
wouldn't want to keep my hand on it.  The fan never came on.

Is this normal?  If so, perhaps firmware should be updated to sporadically
run the fan and suck some air through.

It's not a matter of can't. Why as a customer should I pay for the added
power supply when I'm installing my rig mobile? Or how about if already have
a nice power supply. 
Do you want to increase the cost of the radio which will result in a higher
weight and cost for customers that don't want the feature ?
With economies of scale I don't see how they could make profit or even break
even doing anything with a power supply when  you look at the market.

Dear List,

I need to find a source for the type of 8-pin (male) panel jack, as used on
the K3 and many other ham transceivers. This is for a project to allow
connection of my Elecraft wired mic. Radio Shack used to sell these, but now

I have gotten the MX-P50M up and running with my KX3 keying it OK.  I was
able to get over 50 watts out of the amp into a dummy load with 6 watts from
my KX-3 on 160 meters.  It turns out to be quite simple to configure once I
researched how the amp lead was used for keying with the FT-817 and what the
KX-3 provided for keying.  The KX3 provides keying via the ACC2 connector on
the ring terminal on the 2.5mm stereo plug on an adapter cable.  The KX3
grounds the key line while transmitting to enable the amplifier to be keyed.
All that was needed was a splice into the red/black lead section intended
for the FT-817 DIN connector with a red/black lead terminated with a 2.5mm
stereo plug. The red lead goes to the ring on the 2.5mm stereo plug.  And
that is it.  This took more time to figure out than I wanted.  Obviously, it
would have taken less time if there was a manual with the amp.

Having done the change myself and helping the vendor make the customization for the K2, I would have to recommend the Batteryspace item CU-J1087-V1.

The "V1" connectorization allows for a drop-in incorporating the back panel cutoff switch

There's a thread about all this from late August - early September 2015 that contains verbose detail regarding this topic.

With the hindsight of a year and a half plus experience, I'm even more happy with this setup now than I was then.? I do use their 'matching' charging brick.

Subject: [Elecraft] Audio File Transfer to K3S
Message-ID: <58AB13E4.1090207@arrl.net>

I recall reading something about transferring optimized audio files to 
the K3S, but I can't locate it.

I would like to prepare contest exchanges in a desktop software package 
and move them to the Elecraft digital voice keyer in the K3S.  I would 
like to tranfer these files using the standard K3 Utility or some 
Python-languafe PySerial code.

Can anyone point me to this capability?  I'd liek to complete the work 
by ARRL DX SSB in three weeks.

Hello Joel!

Try

Many thanks to all who replied! It seems as if there are many sources. Based
on the recommendation of Joe Subich, W4TV, I just ordered from Buxcom
(www.packetradio.com), which had both cable and panel types, as well as some
other things I was looking for.

Dear List,

I need to find a source for the type of 8-pin (male) panel jack, as used on
the K3 and many other ham transceivers. This is for a project to allow
connection of my Elecraft wired mic. Radio Shack used to sell these, but now
seems to just have the cable side. If anyone has a mfr name and part number
that I can search for, I'd appreciate it.

Thanks!

Message-ID: <CAHmQzTkQb3bszC8Q_f7LGq62HPxsf0_HmhyraEdsy33cW-D3ew@mail.gmail.com>

Harry

I use the Batteryspace charger recommended for that pack and simply plug it
into the radio.
I had to select the model with the right plug to match the rig.
I flip the battery switch  on the K2 'on' for charging.  The charger shuts
itself off when done.
No radio alterations or anything else are needed.  I did not want to drill
holes or add switches.
I do *not* operate the radio while it is charging, although doing so won't
cause any damage.
The charger is a switching supply and is RF noisy.
The LiFePO4 pack provides 2x to 3x the portable run time that the gel cell
did.
The new pack also appears to have a lower self discharge rate.  I can go
months after a full charge.
For use while at a fixed location I have a RF quiet power supply from Pro
Audio Engineering
<https://proaudioeng.com/products/pae-kx33-low-rfi-ac-power-supply/>.
This power supply does not charge the battery, so, you just flip the
battery switch off.
Oh, I should mention, the new LiFePO4 pack is designed specifically to fit
inside the Elecraft bracket that comes as part of the internal battery kit.
Since I already had that internal battery it was easy to change it out.
If you are doing this from scratch maybe Elecraft will sell you just the
bracket and switch (the kit less the gel cell and wiring which are part of
the internal kit).
If you accidentally leave on the 'regular' power while the battery switch
is on, the battery will not charge fully.

Subject: [Elecraft] Follow-up... Considering KPA500/KAT500 Combo with Flex
	6500
Message-ID: <CAFA9uju6eMSQ1HZNd1mOigrrJEK+C8HLo4LpecGGd1KMuAKY9Q@mail.gmail.com>

I put the new KPA/KAT500 to work with my Flex 6500 this weekend in the
ARRL-DX-CW contest and I had an absolute blast! It was generally a casual
effort but netted 500 contacts, about 90ish being unique DX and qualified
for CW DXCC. I worked 80,40,20,15 (surprisingly productive on 15) and ran
the KPA between 250 and 500 watts. Mostly glitch-free operation.

I did happen to kill my wife's satellite reception. Tech coming this week
to check it out.
?[Tech arrived, wind damage to the dish, not me!] ?
Also, her TV would bring up different menus. This only happened on 40
meters above 190 watts. I will need to drop some ferrites on the various
leads up there and see how that works for her. The neighbors, about 160'
away, didn't complain but I'm bigger than they are so maybe they were too
scared. ;)

I used N1MM+ along with CW Skimmer. I set up the skimmer as a local cluster
and telnet'd to it from N1MM+. The bandmap was useful but the list of
available Qs and Mults was the key. I just worked my way top to bottom
(sorted by newest) and it was like shooting fish in a barrel. I think. I
never really shot a fish in a barrel. But it was very easy to work the
list, see a mult come in and jump on it immediately. At some points I
almost felt like I was in Run mode with how quickly I was nabbing contacts.
Again, it was a real pleasure working this way when everything just snaps
into place.

I have a hex beam for 20 meters. It is only about 10' off the ground on a
roof mount. I really felt the value of the hex finally. When selected over
the dipole the noise level dropped along with most of the signals. While
the S-meter read lower for the signal of interest there was also much less
noise and interference from other signals. I only saved one audio sample
showing dipole/hex a/b while working a Japan station. Not sure if
attachments make it on the reflector but if it does, the first few seconds
is dipole. Then I flip to the hex and  you can dig Japan out of the noise.
Being able to not only copy him but work him successfully was pretty
exciting for me. My QSOs with that part of the world are very rare.

Thanks Elecraft for all the fun. Thanks for making the KPA/KAT combo deal
and making such great equipment. Big thanks for making them valuable even
if not run with an Elecraft rig. I don't think I missed out on a single
feature of the amp/tuner combo running with the Flex.

?Unfortunately the audio was moderated out. ?It's posted here

I operated my K3/100 remotely this weekend in ARRL DX.  I noticed the top of
the case getting pretty warm - not too hot to touch, but warm enough I
wouldn't want to keep my hand on it.  The fan never came on.

Is this normal?  If so, perhaps firmware should be updated to sporadically
run the fan and suck some air through.

 Back in 2013, I purchased a custom shipping box from Dave Haller, KA1W, of www.hamradioboxes.com with which to ship an Acom 1000 amplifier that I was selling.  It was pricy, but so was the amp.  I would not have purchased one for just a half a K3 round trip to Elecraft Service, but if you are doing DXpeditions and moving your gear around regularly, his custom boxes were outstanding.  

Update:  I did a quick Google search for Ham Radio Boxes and the most recent I can find is from 2014 saying that Dave had taken a "temporary break" from the box building business.  Sad, as Dave was excellent to work with.

The discussion was for a custom replacement for the 2.9 Ampere-hour gel

It fits where the gel cell does, in the Elecraft custom internal bracket.
It is almost exactly half the weight.

Message-ID: <CABS7SRCgPcen2iGYeZJ+9oBHq5MARF83J8pD+qqBexvHJhmtYQ@mail.gmail.com>

After years of using the same* station configuration, for the last couple
weeks I have a weird thing that I haven't been able to explain or isolate a
cause for.

Using one of my headsets, the sidetone decreases in volume by at least
about 10 dB during a transmission. Usually it happens quickly but sometimes
gradually. After a short rest it usually resumes its normal volume. It
happens regardless of monitor volume setting. The tone produced when you
adjust the volume is not affected. RX audio is not affected.

It's not 100% due to RFI because it happens even if I have transmit
disabled. It happens regardless of whether I use the rear panel or front
panel jack and regardless of CW/SSB/digital. It does seem to be more likely
to happen when I'm transmitting, though, which is why I say "not 100%" RFI.
Let's just say that the behavior seems to be aggravated by RF or the
fluctuating DC voltage that comes with it. I've checked my bonding and
connectors for tightness and everything seems OK.

The offending headset is a Koss SB/49 that I've used for more than three
years. It doesn't happen with any of my other headsets. One distinguishing
factor is that this set has a high impedance, 280 ohms DC. The other sets
are in the range of 40-120 ohms.

I have found the Microsoft auto-correct system to be far less literate 
than the majority of folks writing text.  It is quite frustrating to 
have to add a half dozen words to its lexicon while I am writing a 
simple email.  Said lexicon includes a few errors which need to be 
corrected.  My high school English teachers would freak.

The short answer is they can. It is only a matter of engineering 
time, cost, resulting price, number of customers and competing 
projects. In other words, the usual business considerations.

Lets work the idea through for several of the Elecraft RF amplifiers:

The 10-15W K3(s) amp: This amp can have significant IMD at low 
voltages as we have discovered with our QRP, all Elecraft, field 
day operation. The KX3 seems to do better, so reengineering the 
amp may be a better solution. For field day, we try to have 
fresh batteries available.

The 100W K3(s) internal amp: This amp also has low voltage IMD 
as we found during our 100W California QSO party expeditions. 
But, consider the K3(s)'s construction. The front of the radio 
is the digital portion, including the DSPs and the front panel 
computer. All of this digital noise is isolated from the analog 
circuits in the back of the radio. If Elecraft were to include a 
boost power supply with the internal amp, that high-current 
switcher would be in the analog section, and probably impossible 
to quiet. Solution: Get an external boost power supply.

The KXPA100 external amp: This form factor would be an ideal 
place to include a boost power supply. The use profile includes 
portable battery operation and designing isolation for the power 
supply into the package seems straight forward.

The KPA500 external amp: The amp setup procedure sets the 
voltage to to 65v to 85v and the specifications call for about 
1000 VA of power or about 13A at 75v. That would be nearly 75A 
at 13.5 volts assuming 100% efficiency, so it would be a good 
idea to put the boost power supply next to the battery and run 
75v to the amp. It would make a nice high power mobil rig.

Now that I am totally doing so2r K3, I have reasons to use the second antenna port available for k3/K3s.  I understand from the K3s manual that the second port works off the internal tuner module.  If I understand correctly, you can bypass the tuner and then select either of the two antenna ports, OR select the tuner for either antenna port.  Is this correct?

I have an old MP that I press into service just to have a radio with a second port for contest-specific but misc. antennas.  An MP, modified like mine, is good but of course it is not a K3.   Actually, dynamic range is acceptable, at least in rural Idaho, but TX phase noise is noticeable in so2r.

Due to my habit of using so2r K3 I may purchase the tuner just to get access to that second port--so long as I am not forced to use the tuner on either port.  Wouldn't it be nice to have a module that allows access to the second port without purchasing the internal tuner?  

I need access to both ports without the tuner, i.e., the tuner is bypassed on either port.  I think this is want the manual is saying but I want to be certain.

I have long wondered why some manufacture did not think of it. ?That is a amp with built in 12 VDC boost PS. ?With all of the new switching tech, it should be a KISS solution and make the amp SOUND GREAT all of the time....

Will,

You are interpreting the manual correct.  The ANT1/2 choice can be made 
independently of whether the KAT3A is in BYPASS or TUNE.

I believe the new Anan-8000DLE does exactly this, and steps up the voltage
to 50V. No idea if there's any noise related to these boost converters.
Seems like a neat idea, just not sure how it will work in practice.

I have a Codan 6924 lunch box radio that does just this.

 (
http://www.hfradiosales.com.au/codan_%20barrett_hf_radio_information/RADIOS/files/6924%20MK2-2.jpg
)

It takes in 10-15V and boosts it to 28V to feed a 25W PA, it does so only
on TX.  This radio was designed in 1969 and released to market in 1971, I
got mine given to me in 1979.  So this concept is not new.   Way back when
the 28V RF transistors of the day did not operate well with low collector
voltages at 12V, IMD was way too high.  For reference the 6924 IMD is
better than -40dB PEP for a 38 yr old radio.

I believe we will see a return of the 50V MOSFET PA's in commercial
equipment again, especially with the explosion of LDMOS devices and the
ever decreasing availability of 16-18V bi-polar RF transistors.

For the rigs running off of 12 (13.8) Vdc, how about simply not running the
rig "all knobs full right"? 

Reducing the power by 25% will improve IMD performance at lower voltages,

And there is little difference in signal strength, might actually be stronger as copy is better and less signal wasted by eliminating IMD, etc.

I'm trying to reconcile this advice with our experience running 
QRP field day. We frequently have two or 3 K3s on a single band 
(CW, SSB, Digital/GOTA). We use batteries and solar cells since 
our site does not permit generators. When the radios are being 
fed from a charged battery or a battery being charged from the 
solar cells, we don't have a significant problem with 
interference between stations. (Antenna placement helps a lot 
too.) When the voltage drops, the complaints increase.

Of course, our 5 watts is quite a bit below the full power of 
the low power RF amp in the K3.

Bill;

To be fair, we have had one instance of the problem, and that station was running the battery critically low. In fact the battery failed at that voltage (something like 10 volts) and had to be permanently removed from service. Perhaps the answer is to take the battery manufacturer?s advice and not to run the batteries below 11.5 volts. I believe the K3 has a low-voltage alarm that can be applied to the problem so that it gives a warning at the critical voltage and won?t continue until the power is corrected.

In general, we have found the K3 to be an excellent performer when running off battery at 12 to 13.8 volts, whether charging or not. Anyone wishing to hear us, just listed for K6EI in Field Day. And for those who wonder, having great antennas 500 or so feet above San Francisco Bay gives us great signals, even at 5 watts.

My favorite CW frequency.  You'll find little/no digital activity on 7035.
Look around 7070.

At my home station I run my transmitters on a "boosted" 14+ V bus using
a TG Electronics Boost Regulator - and "the knobs" at about "3 o'clock".
 The station battery can go as low as 11.5 V but the 14V bus stays there.

This whole topic is very interesting to me. Very ironically, just before
this topic got started, I was thinking about qrp hall of famer, Rick
Littlefield's,  Ham Radio magazine article Mar 89', featuring a resonant cw
speaker.
It was built using a solo 16 cup and a small 700hz transducer.
I put it on my to do list, back in 89'... nearly 28 years later I FINALLY
sent Rick an email asking if he still had any of these little speakers
left, after so many years... A few days later I had a package from Rick
with a couple of the little speakers!
The generosity of old school hams never ceases to amaze me.

I have a question for those in the "know"--

Knowing very little about the physics of sound, does using a thinner tube
as opposed to a larger diameter one, make the tube have a narrower "
bandwidth " ?
How would on increase the Q of the device ( if that's even possible)?

I'd appreciate any input. TIA

See: http://www.fonema.se/qpipe/qpipe.htm

Since the primary loss component of an "organ pipe" is friction along
the wall, a larger diameter tube will have lower losses and thus higher
"Q".

Modern commercial communication sites have all gone to 48V "Bell
Telephone Standard - positive ground" with corresponding radio
equipment.  Inverters for 120V AC and 12/24V DC where needed.  It's a
whole new world for us "old timers".

Thanks for reminding me of the details. The 100W CQP incidents 
and the 5W FD ones get blurred in my mind.

Yes, the K3 has a low voltage warning. The level is controlled 
by the "BAT MIN" CONFIG menu setting with a default of 11V. It 
sends out a beep tone and flashes BAT LOW on the display. If you 
use a boost regulator like the TG Electronics Boost Regulator, 
note that these may introduce a junction voltage drop which will 
cause the warning to sound at a higher voltage.

Subject: [Elecraft]  second receive antenna port of K3
Message-ID: <d49fe7f9fa90c2d7083c951c27531c2e.squirrel@www11.qth.com>

I do not have the internal antenna tuner but I believe that you do not
need the tuner on to access the added antenna port. This is an expensive
option just to add another port and I do not understand what this has to
to with SO2R. I ran SO2R and even SO2V many times using a single antenna
port.

Now that I am totally doing so2r K3, I have reasons to use the second
antenna port available for k3/K3s.  I understand from the K3s manual that
the second port works off the internal tuner module.  If I understand
correctly, you can bypass the tuner and then select either of the two
antenna ports, OR select the tuner for either antenna port.  Is this
correct?

I have an old MP that I press into service just to have a radio with a
second port for contest-specific but misc. antennas.  An MP, modified like
mine, is good but of course it is not a K3.   Actually, dynamic range is
acceptable, at least in rural Idaho, but TX phase noise is noticeable in
so2r.

Due to my habit of using so2r K3 I may purchase the tuner just to get
access to that second port--so long as I am not forced to use the tuner on
either port.  Wouldn't it be nice to have a module that allows access to
the second port without purchasing the internal tuner?

I need access to both ports without the tuner, i.e., the tuner is bypassed
on either port.  I think this is want the manual is saying but I want to
be certain.

Why is it that no manufacturer has created a field replaceable front end 
protection scheme?  Many of us are using multiple radios or in Multiop 
situations.  Stuff happens.

In the case of the K3, D25 which we think has gone bad for whatever 
reason in my radio is a surface mount diode that cost essentially 
nothing but is not easily replaced.  Why?  Is there no way to provide an 
easier user replaceable part or a cost effective protection circuit 
board that would be field replaceable?

We noticed again during the contest hat when 3 or 4 stations called, all 
those signals would be flattened to the same level. Once you got to 
where one or two stations were calling the signal level would pop up 
substantially.

I have played endlessly with slope and threshold with little effect.

My K3 has the new syn boards as well and filters from 2.8 to 2.5.  
Latest firmware etc.

Are others still seeing this issue?

Mile,

Google Buss "Picofuse".  Cushman two-way radio test equipment used to use
them as protection from the inevitable uh-oh's.  Very small, plug-in with
special screw-capped shielded holder.  Might be applicable.

While Ed is having fun on 3.560 I'm having a ball up a kHz or so just beyond 3.561

I worked 5 stations this morning from Manitou Springs, CO on my mcHF QRP transceiver at 5 watts to an EFHW up at 30 feet.
Three of those ops had also worked Ed.

W3KC	CHAS from Damascus, MD - not bad for QRP!!
N5GW	GENE from Vicksburg, MS
WB8ICN	MIKEY from Jackson, MI
AF5DM	DAVE from Plano, TX
K1ND	JAN  from Ypsilanti, MI

I want to thank the operators for their patience and skill in working my QRP station surrounded by the foothills of the Rockies near Pikes Peak.

Its was a thrill to work K1ND and WB8ICN, two Michigan friends I?ve known for years and whom I never had a CW QSO until I moved out here.

This radio stuff is fun even in the doldrums of our current solar cycle!

Sounds like very strong signals with fast agc with its decay set well into
fast range. And if you have stations using spot frequency that will really
muddle them.

I have my fast agc set to its slowest possible decay and my slow agc set to
fastest possible decay. Then I only use the fast in heavy qrn.

Mike,

Think about it - if there are multiple signals in the passband, the AGC 
will respond to the strongest, there is just no way around that fact.
If the signals can be separated by the DSP, and one is really strong, 
that strong station may be activating the Hardware AGC.  The only 
solution for the latter is a more narrow roofing filter - put the 
offending strong signal out of the passband of the roofing filter and 
use shift to get your sidetone for the desired signal back in order.

That may be too much "fiddling" for a run station in a contest, but it 
is a viable way to operate when trying to copy a weak station working 
close to a strong station.

Receiver protectors have been around for a long time.  Drake offered one 
for its line.   It had to be installed at the front end of the receive 
channel, which for most transceivers like the TR-7 required inside after 
the antenna T R switch or relay.

I am trying to get my head around the memory set-up on the K3. Must be 
missing something.
I have set memories (and config) 0-9 as band switches, and that seems to 
be OK; the last frequency I used on each band is stored in memory when I 
go back there, but I put the 40 meter WWV frequency into memory 11, and 
now my 40 meter memory (#1)  shows that frequency when I select it.  How 
can I save a specific frequency in memory, without having it change ?

What "40 meter WWV frequency" - WWV transmits on 5, 10, 15 and 20MHz.
If you want to set a memory to 10MHz WWV, you should select 30 meters, 
tune to 10.000.00 and set the memory from there.

Ramon, Thanks for the advice.  That is probably what my difficulty is; I 
will check when I get back to the rig tonight.

Don, I realized after I sent the message that I meant CHU, (not WWV) but 
did not want to  make another post just for the correction.   The basic 
memory question was valid though, no matter what frequency I was talking 
about.

Greetings to the list!

After many years and much DX, I am retiring my beloved Ten Tec Orion and
have a K3S kit and P3 on the way.  I'm looking forward to building it and
putting it on the air.  I ordered the Sub-RX and dual 400 Hz 8-pole
filters.  More options later perhaps.

I've been licensed since 1983, been pretty serious about DX'ing for a
while.  I'm one away from Honor Roll so the Elecraft should be the one to
get me there.  The home station is pretty modest, a small LPDA at 50 feet,
a Butternut HF9V for low bands, an Inverted-L for Top Band, and K9AY loops
for receive.  I'm putting together a shorty-40 2 element yagi but will have
it low to the ground for now.  I've got a couple of kilowatt amps, one is
for the K3S and the other for the backup rig, a Yaesu FT-1000MP.

I'm just outside Hattiesburg, MS and work for the local university.  I've
got about 3 more years to retirement.

I expect for now I'll likely read more than write, unless I have questions
about the build or the operation.

This has been discussed at length in the SDR groups.

Upon many recommendations, I invested in a DX Engineering DXE-RG-5000
Receiver Guard to protect my SDR (SDRPlay 2).  It is a small box with
BNC input and output connectors.   It is rated for 500 kHz - 150 MHz and
clamps the received signal to 0 dBm, well within the specs of any modern
receiver front end.

Note, however, that it cannot pass any transmit-level RF and there are
copious warnings to not transmit through the device.  It requires either
a separate receive antenna, a separate T/R controlled antenna switch, or
a rig that has RX-ANT-IN an RX-ANT-OUT capability.  The instruction
manual has many diagrams covering each of those situations.

(I am not associated with DX Engineering, just a satisfied customer.)

Subject: Re: [Elecraft] K3 Memory Question

What "40 meter WWV frequency" - WWV transmits on 5, 10, 15 and 20MHz.
If you want to set a memory to 10MHz WWV, you should select 30 meters, tune
to 10.000.00 and set the memory from there.

I would like to see the 3 microphone settings (PTT, Bias, and up/down)
turned off in data mode much the same as the transmit / receive equalizers,
and compression settings are now.

I would also like to add to the list RF Squelch in HF and extend the auto
off timer to 4 hours (in steps) rather than max out at 20 minutes as it is
now.

Thanks,

  Excellent news, Wayne!

  If only you could consider making the "Mic Btn" settings mode-dependent,
my life would be complete (or thereabouts). Right now this is the #1
setting I need to change all the time: when using the Mic on SSB I have to
enable "Ptt", and when switching to DATA to connect my audio card for
digital modes I need to set it to "Off" because the audio card jack I use
keys PTT... :)

Ed,

I don't know what audio card you are using, but if it has a stereo plug 
on the KX3 end of the cable, it should not turn on PTT.
If it does, I suggest you make up a special cable with stereo plugs at 
both ends, and connect only the tip and shell of the plugs.
That should eliminate your problems with PTT being activated in DATA A mode.

  Oh yes, I had forgotten bias as well - ptt/bias/updown should definitely
be mode-dependent so that we can disable all those in DATA mode.

Thanks Mark

Don, that's a great explanation. I came to the same conclusion in a recent
RTTY contest. I built my K3 with the single stock filter based on advice
from a number of folks to 'just operate for awhile til you get the feel for
what other filters you need'. I think that's sound advice.
Anyhow, I've been generally ok with the standard filter and relying on DSP
filtering to narrow it as needed. However, in the RTTY contest, I often had
issues working weaker stations when strong ones were very close by. It was
easy to see what was going on by watching the P3- I'd start copying a
signal inside the DSP bandwidth, and a strong one would pop up just above
or below that station. Even though I couldn't hear the strong station, the
weak one would go nearly silent as the AGC kicked in due to the strong
signal in the IF passband.
So, I think I've learned that I need a narrower filter for such situations.
I'm thinking a 400hz filter is what I want. Any reason for a different
selection in that scenario?

Hello

I am trying JT65. Two audio cables from LINE IN and OUT in the K3 to phones
and mic in the computer

I can see decoding on the software, but I cannot get RF out. The K3 go to
TX, but I think is not sending RF. I increase RF while TX and I dont see RF
out on the K3 smeter

Any help?

Jorge,

JT65 is "just another data mode", and like other data modes, you must 
drive the K3 audio up until you have 4 bars solid on the ALC meter with 
the 5th bar flashing.
Adjust the computer soundcard output and the K3 LINE IN Gain to achieve 
that condition.  You do not have to transmit while making that 
adjustment, set the K3 to TX TEST or turn the power to zero.

Then adjust your desired power level with the power knob.

I know this differs from the common internet (and some software 
instructions) which say to set the power to full and use the audio level 
to control the power.  That advice is for rigs other than Elecraft.
That does not work with the K3 (or other Elecraft rigs).
Elecraft controls the power differently than other transceivers - the 
firmware adjusts to the power set with the power knob rather than merely 
controlling the drive with a knob.

Dave,

Yes, a 400Hz filter will work well for RTTY (and CW too).

I'm pretty much full time CW and rarely leave the 400 Hz filter.

Yes, a 400Hz filter will work well for RTTY (and CW too).

I haven?t tried this yet specifically to see if it can outwit the AGC, but it is often useful to flip to CW reverse to get the QRMer on the other side of the skirt.

But during a contest, like this past weekend, when no-one is supposed to be operating split, I don?t know how much an S&P station can do to dig under strong callers who are spot on the target.

    Mike,
    
    Think about it - if there are multiple signals in the passband, the AGC 
    will respond to the strongest, there is just no way around that fact.
    If the signals can be separated by the DSP, and one is really strong, 
    that strong station may be activating the Hardware AGC.  The only 
    solution for the latter is a more narrow roofing filter - put the 
    offending strong signal out of the passband of the roofing filter and 
    use shift to get your sidetone for the desired signal back in order.
    
    That may be too much "fiddling" for a run station in a contest, but it 
    is a viable way to operate when trying to copy a weak station working 
    close to a strong station.

Thanks Don

what mode do you use? DATA - DATA A?  USB?

In USB mode with MIC know I adjust LINE but no bars on the ALC meter.
Maybe something with the notebook soundcard, thats is very hard for me. I
will trying to figure out about the computer, or try to get a USB external
soundcard

thanks,
Jorge

Jorge,

As with all data modes, use DATA A.  It should be the same as USB, but 
with compression and TX EQ disabled.

The DATA A mode MIC SEL should be set to LINE.

Adjust the computer soundcard output to at least 75% and then adjust the 
MIC Gain (actually Line in gain) to achieve the proper number of ALC bars.

73,
Don W3FPR

Most everyone missed the point.

Why in the K3 is there not an easy way to replace the damaged protection 
diode or any radio for that matter.  This would seem like a common 
failure point for many people using 2nd rigs, dxpeditions, etc.  Maybe 
it is not practical in the actual sense? I don't want to drag more stuff 
around.  If would seem to me that providing a field replaceable item on 
the radio would not be that difficult.  Maybe it is?

I can run with 400 or 250hz filters.

I have tried it with AGC fast, slow off etc.

I just think this is something that most people just never see. This was 
a major point of discussion a while back.  I guess it is just the way 
the radio is.  I will have to try another rig to see if I notice the 
same effects.

In a pileup there is no offending station they are all calling me.

I was just curious if other contesters or DXpeditioners settings might 
be and if they are still seeing this issue.

Hello

I am trying JT65. Two audio cables from LINE IN and OUT in the K3 to phones
and mic in the computer

I can see decoding on the software, but I cannot get RF out. The K3 go to
TX, but I think is not sending RF. I increase RF while TX and I dont see RF
out on the K3 smeter

Any help?

thanks,

I was several releases back and just installed this beta so my question
probably applies to an earlier release.

I was dismayed to see that frequency display resolution (all 3 of them) is
now down to the the single Hz! That's three decimal places. I always
thought two decimal places was too many, given the typical resolution of
the display. Is there a way to truncate this, say to the nearest one KHz?
Even the P3 only goes down to hundreds of Hz. This is a radio, not a
laboratory instrument!

I replaced that diode in my K3 with instructions from an Elecraft technican-person. I also at the point purchased bandpass filters so that I didn't have to worry about that happening again.  

In fact, all repairs and some mods to my first and early K3 were done by me with Elecraft assistance until I sent the radio back to get the new synthesizers and repair a problem that turned out to be a nick on a trace that disabled the sensor for the PA fan....that problem must have happened when I moved and the radio got some rough handling. I didn't even notice the problem until I started using more than 50 watts output.

The replacement of the diode isn't difficult even if you didn't build your K3. My K3 was factory built.  The tech-guys that tell you exactly what to do is a novel approach to service that has worked well for me.

 Most everyone missed the
 point.
 
 Why in the K3 is
 there not an easy way to replace the damaged protection 
 diode or any radio for that matter.? This
 would seem like a common 
 failure point for
 many people using 2nd rigs, dxpeditions, etc.? Maybe 
 it is not practical in the actual sense? I
 don't want to drag more stuff 
 around.?
 If would seem to me that providing a field replaceable item
 on 
 the radio would not be that difficult.?
 Maybe it is?

Amen to that whole list. Well, HF squelch would be awesome, but that is complicated.

Longer auto-off would be lovely. My KX3 kept turning itself off while I was listening to Radio Havana Cuba, so I changed it to INFINITE. Last night, my lovely wife, the light of my life, was annoyed by the display being on in our bedroom while the batteries were charging, so she turned off the large, linear power supply. The KX3 happily switched to running off batteries and was at BAT MIN by morning, with the light still on. So that didn?t work out well for anyone, including the Eneloops.

60 minutes would be great for me, so I recommend 120. Or four hours, whatever.

Re-posting from April 2016, and earlier:

73 from Ian GM3SEK


***************

The factory default AGC THReshold for the K3 and K3S is very, very low.
Measurements by KE7X [1] have shown that the default setting of THR=5
corresponds to an AGC onset at less than S3, whereas competing rigs have
a threshold of S7 or even higher. This very low AGC threshold is what
allows the AGC to be activated by band noise.

Elecraft's factory defaults of THR=5 and SLP=12 compress all signals
above the AGC threshold into a very narrow range of audio output levels
[see the measurements by KE7X]. This makes for comfortable
broadcast-style listening - but there is price to be paid. The default
settings tend to hide the real-life differences in the strengths of
incoming signals - important differences that DXers and contesters
*need* to hear, in order to pick individual signals out of a pileup.

Following complaints from DXers, DXpeditioners and contesters about this
so-called "pileup mush", and following further series of measurements by
KE7X, Elecraft eventually did increase the available range of AGC
THReshold settings (the v4.51 firmware upgrade). 

Following the release of FW v4.51, the consensus within the
[K3-contesting] Yahoo group about the most important settings for DXing
and contesting has been as follows. 

* AGC THR: increase to at least 8 (from default = 5) and preferably to
12, and then take some time to become re-accustomed to the increased
range of audio levels [2]. (Some users recommend as high as 14, if your
ears can handle it.)

* AGC SLP: decrease to 8 or even less (from default = 12). Lower SLP
settings allow stronger signals to sound somewhat louder, and thus more
realistic, but the range of variation will be partly determined by the
THR setting already made; so always experiment with THR first, and with
SLP afterwards. 

* AGC DCY = SOFT (not default=NOR). The User Manual claims that "The
SOFT setting can reduce IMD caused by traditional AGC, and is especially
useful in 'pileup' conditions, in some cases making it unnecessary to
turn AGC off."
 
The settings recommended above have essentially solved the problem of
"pileup mush" for those who have tried them... but regrettably, Elecraft
has done almost nothing to make DXers and contesters  aware that such
changes are possible. 
 
More than 3 years after the firmware release notes boasted that v4.51
"greatly improves signal clarity in pile-ups and other high-noise or
dense-signal situations, especially with threshold set to 12 or higher",
that information is *still* missing from the User Manual. There is also
no information on how to create different 'profiles' of AGC settings for
different types of users.

Meanwhile, Elecraft's factory AGC defaults remain exactly as they were,
still optimized apparently for comfortable 'listening', while many DXers
and contesters remain unaware that their K3/K3S could actually be *so*
much better. 



[1] http://www.ke7x.com/home/miscellaneous-k3-information

[2] It is important to give any increased AGC THReshold setting an
extended trial. To anyone accustomed to an artificially restricted range
of audio signal levels, a higher setting will initially sound quite
'aggressive' - even though the new setting is much closer to real life.

Jean,
      I have two of the EA3BLQ board sets.  One set has the boards assembled
and the second set is unassembled.  I also have the specific connectors and
everything needed for a full installation of the boards.  Since I obtained
the boards I have acquired a K3 and do not want to do any mods to my K2.
Please let me know if either set interests you.  73.

Hi K2 users;

We all now that the digital interface realised especially for the K2 by
EA3BLQ in past,is SK despite !

A lot of time is gone,but are there some alternated suggestions,about the
building concept of EA3BLQ.

I can imagine that someone has continues his PCB art work for further K2
digital interface users .
I personally not need for my own purpose.

I do have build a ON4AEF external digital interface for my own into a second
K2 box (Don W3PFR now about my concept hi) .  

But a friend of mine who also have a K2 and he like to build a digital
interface circuit for his K2 like EA3BLQ has build.

He prefer the design of EA3BLQ but he needs some PCB's of Pedro.

>From there my request if someone has some dupes EA3BLQ boards or are there
some copies released around his project hi ..

Kindly regards es thanks anyway

I remember this, and had forgotten what I set them at. I just looked and 
I see that I have SLP=003 and THR=14! That is practically no AGC at all. 
In contests I sometimes turn up the SLP to protect my ears, but for 
normal DXing this is what I've gotten used to and I like it.

I am surprised that you think it is not possible to accidentally set the
bandpass filter to the wrong band or have an automatic switching relay
fail, have a control wire pull out or just plain cockpit error after
operating sleep deprived?  W0MU has a good point, if you're operating away
from home like many of us do it could be a nice feature.

I replaced that diode in my K3 with instructions from an Elecraft
technican-person. I also at the point purchased bandpass filters so that I
didn't have to worry about that happening again.

Jean,
     The message below was sent to all three email addresses you provided.
I will include it here so hopefully you will receive the message.

Doug W4DAS

Jean,
     I am sorry that I have not responded to your earlier email.  I was sick
for some time and did not pay much attention to emails.   I would sell the
assembled EA3BLQ board with the pieces needed to integrate it into the K2
for $150.  The unassembled kit with the same parts for integration would be
$120.  I can accept payments through Paypal at account name
w4das at comcast.net .  I will pay for the postage.  Please let me know if I
can help.

Dave,
     I do lots of rtty contesting.  I have found the 400Hz filter to be 
just right for rtty.  The 250 is too narrow.  I then narrow the DSP 
filter to 300Hz if needed, with the 400Hz Xtal filter in front.

While Ed is having fun on 3.560 I'm having a ball up a kHz or so just beyond 3.561

I worked 3 stations this morning from Manitou Springs, CO on my mcHF QRP transceiver at 5 watts to an EFHW up at 30 feet.

N4ELM	BILL from Lafayette, LA
AB8DF	ED from Waterford, MI
K8CV	WALT from Royal Oak, MI

I want to thank the operators for their patience and skill in working my QRP station surrounded by the foothills of the Rockies near Pikes Peak.

It was very neat to work Walt K8CV whom I often joined as a  checkin to the MI QRP Net long before I moved out here from Waterford, MI.

This radio stuff is fun even in the doldrums of our current solar cycle!

Actually it's not the 250 Hz roofing filter that is too narrow, it is the
250 Hz DSP filter setting. If you ignore the label on the roofing filter
and configure the K3 to switch the 250 Hz crystal filter in at the 350 Hz
DSP setting, the combination (350 Hz DSP, 250 Hz roofing filter) works fine
for those situations where there is a very strong signal right next door.
The rest of the time I prefer to operate with a 400-450 Hz DSP bandwidth
and a 500 Hz roofing filter.

Thanks.

My threshhold was at 8  I have moved it up to 12.  Slope was zero but I 
change it all the time hoping for a miracle!  HI!

I am going to have to borrow another rig when I get back and see if I 
see the same things on another brand.

Trying to change out a SMD part on a DXpedition is not easy.   In my 
case I am not sure that D25 is the problem.  Sure I could pull that part 
out only if I had thought to order some and bring along along with the 
proper tools to resolder a tiny part.

I am asking for a simple field solution such as a socket where you can 
insert or remove a diode, etc or even a complete protection module for a 
reasonable price that could be simply removed and a new one plugged in.

I have no idea how to cure a "zizzy," but I was told I had hum on my SSB 
signal after 6 years of perfect audio. Re-flowing the solder joints in 
the MH3 cured it.  Whiskers, maybe.

The issue went away when I reloaded r53 firmware and came back with r57. I
emphasize that the effect is very small and would be missed by most
listeners except for some very critical listeners. One friend said it
sounded like a clatter mechanical noise rather than a fan. Once you are
aware of it, you hear it routinely. It's not a deal breaker, just an anomaly
that might be explained and eliminated by the firmware guys.

Thanks Ian I was about to point out those AGC data but you beat me to it.

To emphasize the comments on SLP a bit, SLP = 0 gives you the best discrimination between signals of different strength ABOVE the THR level.  When working a pileup I want that.  Setting SLP=15  is a flat slope and makes signals of different level sound the same.  You might want that for general rag chewing.  However, since version 4.51, higher THR levels also affect SLP.  For high THR, SLP=0 and SLP=15 are virtually the same. Alan explained that once but I'm not sure why that is so.


BTW, it is easy to make macros to switch between different THR/SLP values for different operating conditions.


Cheers,

Fred KE7X

Re-posting from April 2016, and earlier:

73 from Ian GM3SEK


***************

The factory default AGC THReshold for the K3 and K3S is very, very low.
Measurements by KE7X [1] have shown that the default setting of THR=5
corresponds to an AGC onset at less than S3, whereas competing rigs have
a threshold of S7 or even higher. This very low AGC threshold is what
allows the AGC to be activated by band noise.

Elecraft's factory defaults of THR=5 and SLP=12 compress all signals
above the AGC threshold into a very narrow range of audio output levels
[see the measurements by KE7X]. This makes for comfortable
broadcast-style listening - but there is price to be paid. The default
settings tend to hide the real-life differences in the strengths of
incoming signals - important differences that DXers and contesters
*need* to hear, in order to pick individual signals out of a pileup.

Following complaints from DXers, DXpeditioners and contesters about this
so-called "pileup mush", and following further series of measurements by
KE7X, Elecraft eventually did increase the available range of AGC
THReshold settings (the v4.51 firmware upgrade).

Following the release of FW v4.51, the consensus within the
[K3-contesting] Yahoo group about the most important settings for DXing
and contesting has been as follows.

* AGC THR: increase to at least 8 (from default = 5) and preferably to
12, and then take some time to become re-accustomed to the increased
range of audio levels [2]. (Some users recommend as high as 14, if your
ears can handle it.)

* AGC SLP: decrease to 8 or even less (from default = 12). Lower SLP
settings allow stronger signals to sound somewhat louder, and thus more
realistic, but the range of variation will be partly determined by the
THR setting already made; so always experiment with THR first, and with
SLP afterwards.

* AGC DCY = SOFT (not default=NOR). The User Manual claims that "The
SOFT setting can reduce IMD caused by traditional AGC, and is especially
useful in 'pileup' conditions, in some cases making it unnecessary to
turn AGC off."

The settings recommended above have essentially solved the problem of
"pileup mush" for those who have tried them... but regrettably, Elecraft
has done almost nothing to make DXers and contesters  aware that such
changes are possible.

More than 3 years after the firmware release notes boasted that v4.51
"greatly improves signal clarity in pile-ups and other high-noise or
dense-signal situations, especially with threshold set to 12 or higher",
that information is *still* missing from the User Manual. There is also
no information on how to create different 'profiles' of AGC settings for
different types of users.

Meanwhile, Elecraft's factory AGC defaults remain exactly as they were,
still optimized apparently for comfortable 'listening', while many DXers
and contesters remain unaware that their K3/K3S could actually be *so*
much better.



[1] http://www.ke7x.com/home/miscellaneous-k3-information

[2] It is important to give any increased AGC THReshold setting an
extended trial. To anyone accustomed to an artificially restricted range
of audio signal levels, a higher setting will initially sound quite
'aggressive' - even though the new setting is much closer to real life.

Yes, I have assigned SLP & THR to M1 tap & M1 hold. Then tap or hold M1 
and dial in the SLP or THR value as needed.

I experienced the mush as well and then rode the RF gain.

The problem is due to AGC reacting way too fast when in FAST. It seems that
higher HLD should solve the issue but it does not. I am wondering whether
HLD is applicable to AGC SLOW only? If so, the other choice is to reprogram
AGC SLOW, as K2AV does. Perhaps it completely solves the problem, as Guys
writes that he uses the fast AGC only during QRN. 

I am not sure whether AGC is mode specific as AGC slow needs to be really
slower for SSB and casual operation. If AGC is not mode specific, this means
reprogramming AGC SLOW before and after every contest. 

Ignacy, NO9E

Hello.
My K3 won't RTTY on WARC bands.
Using WinTest + MTTY
All other bands are OK.
But WARC no.
K3 going into TX mode but no any RTTY sound.
Is it K3 setting or WinTest+MTTY problem?

Message-ID: <CA+SkHY5wNsAx7h2+iaUqsJOAJ3PFCyxLtmJGcYh3ctxs1L5ZDw@mail.gmail.com>

Hi everybody,

Following the advice in one of the posts here, I have changed the AGC
settings on my K3+ ( new sync and IO boards as per Elecraft mods kit
turning the old K3 actually into K3S). I've put the AGC THR to 12, AGS SLP
to 8, AGC DCY to SOFT in the Config menu.
Whaw! The efffect was immediate ,very obvious and pleasant! The strong
signals were strong, the weak were weak , but there was no pile-up mush!
What was especially of great importance for me - the long time annoying
problem of receiver hiss and humm when receiving on narrow band 250 Hz
filter was gone! Before, when switching the narrow filter on on weak
signals on the noisy band the signal actually was totally covered by the
increased noise in the filter. I think now it was due to the AGC reacting
to the noise and amplifying it in the narrow band mode because of the too
low AGC THR setting. When the threashhold was increased, the AGC stopped
equalizing the noise and only work on the signal. The result was awsome!
You switch the 250 hz roofing filter on and all the noise and interfering
stns are gone, and the signal you want is there! It could be a very loud
one or a weak one , but it is there and the noise is not!
I recommend everybody to try out this and experiment with the AGC settings
on your K3 radios!

When I change the AGC settings to those recommended to minimize the mush:

* AGC THR: increase to at least 8 

* AGC SLP: decrease to 8 or even less 

* AGC DCY = SOFT (not default=NOR). 

It seems to my ears that I am hearing louder clicks when the K3 switches
back to receive (CW of course). I know the clicks were a problem lots of
folks commented on a few years ago.

To clarify, the issue is there with r57 and not there with r53. I did restore
the configuration of the rig to a previous configuration which was free of
the anomaly, just to reload any parameters that might have changed with the
install of r57, but that did not help.
So...since it's so small and hard to notice by the casual, I won't worry
about it, but thought that it was worth mentioning as an unwanted artifact
of r57. And I don't know which portion of the newest firmware is causing it,
the MCU, FPF, or DSP1,2.

I had a problem with clicks on return to receive with older firmware,

Seeing how the KPA- 500 tends to need less than 25 watts to drive it to full output (500 watts) It got me thinking about a 25 watt PA Option.?
Would it be possible to replace the existing 10 watt PA board with a 25 watt PA board that would use a larger heatsink instead of the case.

If the stock Filters and Relays can handle the 25 watts it would seem that it would be a more inexpensive option for those who plan on going with the KPA500.

Just a thought...

I'm dealing with indoor and hidden antennas for the next few years, 25
watts makes it much easier to stay within uncontrolled exposure limits
than 100 watts. 25 watts is much more appropriate for my confined urban
environment. It's also enough to have fun with the CW and digital modes
I enjoy. I get nervous pushing my KX3 past 5 watts some of the 100% duty
cycle digital modes. However, I would feel much more comfortable with a
desktop rig that could push 25 watts all day long.*

* Right now I'm debating between a 100 watt rig and trying to keep my
fingers off of the power knob or saving my money in hopes that something
better is on the market after I move.

To make this idea work you need to make a 25Wpep amplifier that is kept in
it's linear region so that the IMD from this amplifier does not cause
problems in the output of the KPA500.

To make a class A-B 25W amplifier such as this with enough linearity will
result in you designing an amplifier capable of 100Wpep at full smoke.  The
non-linear nature of HF PA's is easily found on the net.  Having designed
PA's for HF manpacks a number of years ago we simply turned down our
100Wpep design to 25Wpep and pocketed the performance increase at the
expense of cost.

The K3/100 at 25-35W has excellent linearity (highly likely by design, pat
designers on back for this one) which allows a more aggressive approach
within the KPA500 for grunt at the expense of "some" linearity.   You're
not increasing the cost of the KPA500 trying to eeek out every last bit of
linearity to get around the rubbish coming from the transceiver.

I'm keen to do some measurements in the near future of the SPE 1.3k-fa
amplifier being driven by a K3/10.  Having measured the IMD of my the
K3/100 at 10W (KPA3 disabled) recently I was a little surprised at the
result, it was not as clean as when driven at 30W with the KPA3 enabled.
I'd not be surprised to see some output degradation in the SPE from the
K3/10 c.f K3/100 driven at 20W with a -3dB inline attenuator.   This would
certainly explain some of the "wide" local signals that I've been seeing in
my SDR recently.

Engineering is always about compromise, and cascaded amplifiers are one of
the more trickier things to strike the right balance with.

Hi Fred,

I think that's fairly easy to explain. *Below* threshold the AGC does not
act at all so the SLP settings *should* have no effect. It comes into effect
as soon as signal rises above threshold.

Thumbs up here to this reply!

Also, if you have 25 watts max from the rig then you limit your ability to reduce to 100 watts or less where its more than enough.

Remembering that we use the least amount of power needed to maintain the contact.  Just because the gas peddle goes as far as the floor doesn't mean it needs to be pushed that far to get to the shops!

To make this idea work you need to make a 25Wpep amplifier that is kept in
it's linear region so that the IMD from this amplifier does not cause
problems in the output of the KPA500.

To make a class A-B 25W amplifier such as this with enough linearity will
result in you designing an amplifier capable of 100Wpep at full smoke.  The
non-linear nature of HF PA's is easily found on the net.  Having designed
PA's for HF manpacks a number of years ago we simply turned down our
100Wpep design to 25Wpep and pocketed the performance increase at the
expense of cost.

The K3/100 at 25-35W has excellent linearity (highly likely by design, pat
designers on back for this one) which allows a more aggressive approach
within the KPA500 for grunt at the expense of "some" linearity.   You're
not increasing the cost of the KPA500 trying to eeek out every last bit of
linearity to get around the rubbish coming from the transceiver.

I'm keen to do some measurements in the near future of the SPE 1.3k-fa
amplifier being driven by a K3/10.  Having measured the IMD of my the
K3/100 at 10W (KPA3 disabled) recently I was a little surprised at the
result, it was not as clean as when driven at 30W with the KPA3 enabled.
I'd not be surprised to see some output degradation in the SPE from the
K3/10 c.f K3/100 driven at 20W with a -3dB inline attenuator.   This would
certainly explain some of the "wide" local signals that I've been seeing in
my SDR recently.

Engineering is always about compromise, and cascaded amplifiers are one of
the more trickier things to strike the right balance with.

Hi,

Very good points indeed. I am not surprised at all that the KPA3 is much
cleaner at 30W than the K3/10 is at 10W. At 25/30W it's loafing along close
to its optimum IMD level and the "driver" (the KPA3/10) is loafing along at
3W or less. So let's face it, neither of these amplifiers are very linear at
their rated full power levels. So please don't let KPA500 users worsen their
IMD levels by skimping on its driving source.

Hi again,

If I could amplify that a bit further, no pun intended, if you can afford
the KPA500, you surely can afford the KPA3 option in the K3. And it is a
better driver option for the KPA500.

Excellent replies so far.

What we start with is a ten watt radio.  We add the KPA3, which provides 
a jump in output by 10 db.  We can add the KPA500 which provides another 
~12 db; because you're now loafing the KPA3, keeping linearity 
'manageable'.  (Yes, you can push the KPA500 to 600 watts on many bands, 
but the IMD gives less return on that power investment.)

This has been very successful as a model for Elecraft.  I don't see any 
need for it to change (but without restarting another thread, a KPA1500 
with a KAT1500 matching tuner *would* be awesome).

If the user wants to run at 25 watts, use a K3(s)/100.  It's a simple 
macro, computer command or knob twist to reach 25 watts and the signal 
will be sparkling clean.  But I also note that if 25 watts was a hard 
limit, my KPA500 could not be driven to full output on all bands, a 
couple require more input.

Let's not mess with success... This is one case that fewer options (not 
having a 25 watt amp at max OR having it biased into class A, using more 
energy) is a good thing.

73,

Rick wa6nhc

In keeping with my purchasing habits (I own the K1/2 and KX line) I'd rather see a compact, efficient, external, 1 W in /25W out (14dB) packer type amp offered to compliment my very versatile station. Just saying.

+1 on this.
~25w, (optional) built in battery pack and tuner. Integration with the KX2
,KX3 and maybe the K2 and K3(S) for automatic band changing and so on. That
would be awesome.

Have you done the RF exposure calcs?  I have the same issues.  It turns out that on all HF bands, it is difficult to exceed the limits at 100 watts.  Just 5 to 10 ft from the antenna provides enough distance.

New owner here of an Elecraft KX2.
I would enjoy seeing any pictures of the LowePro CS60 (the larger of the two suggested bags) all packed and ready to go, including the rig, paddles, antenna connection and two 25'-long ant and gnd wires, extra battery, and earphones or earbuds.

And what do the letters OFS mean on the B knob?

I am a little late to the Elecraft party, why does this transceiver use a
separate 100 watt module instead of just having a 100 to 200 watt
transmitter like other manufactures?

John KK9A

Seeing how the KPA- 500 tends to need less than 25 watts to drive it to
full output (500 watts) It got me thinking about a 25 watt PA Option.
Would it be possible to replace the existing 10 watt PA board with a 25
watt PA board that would use a larger heatsink instead of the case.

If the stock Filters and Relays can handle the 25 watts it would seem that
it would be a more inexpensive option for those who plan on going with the
KPA500.

Just a thought...

I set the TX GATE to ON 10 and the complaints have been eliminated...although
one fellow is still straining to hear something. I have always had the TX
GATE set to OFF 0 and have over the years gotten complaints of almost
imperceptible "ghosts on the audio", and then this "tiny rattle". Maybe I
always needed to have the TX GATE set to ON. I don't have any noise in the
room, fans or anything, kind of wondered about magnetic noise in the Shure
57 mic from all these monitors, wifi, etc. around here that you can't hear

I'll take a guess.

All transmitters have multiple stages to get to 100-200 watts. Tapping off
the 10w stage was easy to do and makes a nice QRP rig. I used my K3 for
several years as QRP only before getting the 100w amp and eventually the
KPA/KAT combo.

John,

Historically, Elecraft has always offered options - on the premise that 
"if you don't need/want it, you don't have to buy it".
As a result, the KPA3, KAT3, Bandpass filters for general coverage, 2nd 
receiver, DVR, extra roofing filters are optional.

For instance, those who want a transceiver only to drive VHF/UHF 
transceivers do not want to buy the 100 watt PA, nor the KAT3.  Those 
who operate only QRP levels can pay for a K3S without the KPA3.

Certainly, it makes customizing your order a bit more involved, but you 
end up with a transceiver that is tailored to your needs and operating 
preferences.

Don W3FPR

Ted,

There already is a difference.  K3 Utility figures out which you have 
and loads the matching firmware when there is a difference.  It should 
be seamless whether you have a K3 or K3S.

And 25w isn't sufficient to drive the KPA to full power on all bands.

Perhaps what I should have said is that the slope of the gain curve for a given value of SLP changes as THR gets higher.  See the curve at http://www.ke7x.com/home/miscellaneous-k3-information/agc-4-51

As you can see, when THR is 20, the curve for SLP=15, SLP=7, and SLP=0 are virtually identical.  For lower THR levels, you can see the affect of different SLP values.


Cheers,

Fred

Hi Fred,

I think that's fairly easy to explain. *Below* threshold the AGC does not
act at all so the SLP settings *should* have no effect. It comes into effect
as soon as signal rises above threshold.

Hi Dan,

You can go into the AGC SLP menu and then do a sequence of UP; and DN; commands to arrive at your final value.  The strategy for these types of macros is to drive the parameter to one end, e.g. 15 UP; commands set SLP=15 and then 5 DN; changes it back to 10, if that's the value you want.


Cheers,

Fred KE7X

I see how you can write a macro to set Threshold settings, but how is that done with Slope settings?

What happens when you turn the AGC off and ride the rf gain?  Do these 
setting still have some effect or should they be set up differently?

I assume when you use 12/8/soft most people are using AGC-F?

Just by way of an update to the screen printing disappearing, the UK dealer
is going to replace the front panel of the KX2 for me.

Subject: [Elecraft] Product Idea - 25 Watt PA for the K3
Message-ID: <163709C907CA4186822C4710EA556411@LAPTOPEPVQLR1I>

I think this issue of distortion when driving amps at near their limit was 
highlighted early on by a change Elecraft made on the K3.  Initially the K3 
could be dialed up to 110 watts.  However, IMD got pretty rough at that 
level.  So, Elecraft dropped the maximum down to just 100 watts, and the 
difference was quite noticeable.  I tend to run my K3 (when operating 
barefoot) at only about 90 watts hoping I'm doing even better.

I can, and have, run my KPA500 just using a KX3 or KX2 to drive it. 
However, that means cranking the little rigs up near maximum to get much out 
of the bigger amp.  I suspect that is a problem as to IMD.  If I put a 
KXPA100 in between, I also suspect I am much better off in that department. 
So, if I want to play with the little rigs and the big amp, I put the 
KXPA100 in the mix.  As best as I can tell, everything stays pretty 
"linear".  The little rigs only need a few watts to drive the KXPA100, and 
the KXPA100 only needs about 25 watts to drive the KPA500.  Convoluted 
perhaps, but kind of fun to play with.  It does minimize what I have 
directly in front of me on the desk.  I love my K3, but there are 
times/situations when I don't need everything it gives me.

That is correct. While typically in the 25-35 W range, It can require up to the 
low 40 W range in some cases.

The transfer characteristic is pretty linear from an input signal of nearly -120 dBm to about -45 dBm with AGC off.  Signals above that are being clipped by some other non-linear process, probably the hardware AGC.    I don't remember if I had the AF LIM on when I took these data.

Cheers,

What happens when you turn the AGC off and ride the rf gain?  Do these
setting still have some effect or should they be set up differently?

I assume when you use 12/8/soft most people are using AGC-F?

Message-ID: <201702232000.v1NK0v1d006027@mail46c28.carrierzone.com>

I originally purchased a K3/10 which limits output at 12w (how 
linear?).  Then a year ago I bought the KXPA100 which drives to 100w 
with about 5w which is 42% of max output and should be much more 
linear out of the K3.  I haven't determined the drive required for 
25w output from the KXPA100 but is probably down near 2-3w.  I run 
11w on 6m to drive a Harris 1kW amp and run the K3 at 1.3w and use 
the 3-dB attn input to the KXPA100 to get down to 11w.

I'm not running SSB so linearity is less important though JT65a still 
wants a linear amp (6m 1kW is for eme which is digital).

At some point I want to run 6m-SSB and thinking to run with 500w 
measured carrier output; that would realize 1000w PEP and stay under 
the 1600w limit of the Harris.  I do not run the Harris on SSB 
currently due to the five fans making too much audio noise in the 
shack for an open mic (I plan to remotely install the amp at the 
tower base next summer).

I like that the K3 is modular so I buy the options I want (though it seems like I want all of them eventually).


I came pretty close to buying a second K3 and keeping it at 10 watts for use with Transverters (may still happen someday).

I'd like to see Elecraft update their Transverters to match the K3, It is nice to look across my desk and see matching gear.

John,

Historically, Elecraft has always offered options - on the premise that 
"if you don't need/want it, you don't have to buy it".
As a result, the KPA3, KAT3, Bandpass filters for general coverage, 2nd 
receiver, DVR, extra roofing filters are optional.

For instance, those who want a transceiver only to drive VHF/UHF 
transceivers do not want to buy the 100 watt PA, nor the KAT3.? Those 
who operate only QRP levels can pay for a K3S without the KPA3.

Certainly, it makes customizing your order a bit more involved, but you 
end up with a transceiver that is tailored to your needs and operating 
preferences.

Don W3FPR

The hardware AGC engages at about -45 (S9 + 20 dB).  That is most
certainly the final flattening you are seeing in the transfer
characteristic.

Otherwise the slope for each slp setting will generate roughly parallel
transfer curves from the threshold point (witness the parallel curves
for all of the SLP 15 cases as well as for Thr 8, SLP 7 and THR 15,
SLP 7).  K8ZOA produced similar curves showing parallel behavior with
SLP held constant as the threshold is changed.  See:
   <http://www.cliftonlaboratories.com/elecraft_k3_agc_and_s-meter.htm>

Jack also derived charts showing the change in output (audio) level
per 10 dB of input (RF) level for each value of slope (SLP) and the
signal level for  AGC Threshold (THR).  That information can be found
in the same article.  Unfortunately, Jack's data is from very early
firmware and was not repeated after the firmware was never updated to
include values for THR greater than 8.

Message-ID: <4d4c4659-c6b1-11f8-86ce-cf2636062df5@gmail.com>

The only measurements I have seen are from N0CU:

1W        -36dB

4W        -31dB

4,5W    -33dB

6W        -34dB

8W        -25dB

10W        -21dB

Several anwers said this IS NOT normal.

Are there measures which ARE normal?

I am looking for a midway 4...6W values to feed

kW amplifier without additional 100W PA.

Running DC input voltage close to the specified limit of 15.0 V will improve
IMD.  Perhaps the results you posted were with lower input voltage.

Maybe so. I think it would be nice if you could control when the 100w PA
switches on or perhaps just have it one all of the time.

Subject: [Elecraft] PX3 firmware version 1.48 now available for download
Message-ID: <1487889617237-7627320.post@n2.nabble.com>

PX3 firmware revision 1.48 is now available for download as a general release
using the PX3 Utility.  This version is essentially the previous beta 1.45
along with a few minor fixes and one additional feature.  There is a new
version of the PX3 Programmer's Reference (rev A6) as well a new errata
(A8-1), which are both available from the Elecraft website. 

Release notes for this version: 

MCU 1.48 / 02/08/2017

Note: refer to the latest PX3 manual and PX3 Programmer's Reference for more
information regarding these new features. 

* Adds: USB MSD (mass storage device, memory stick, thumb drive) support. 
Most types of flash drives are supported.  Added a new sub-menu called ?MSD
menu? which includes the following features:  
	+ Scrn shot ? takes a .bmp screen shot of the current screen.  
	+ ConfgSave ? saves the current configuration. 
	+ ConfgRstr ? restores the configuration. 
	+ XportMacr ? exports macros/text messages to a file which can be edited.
	+ ImprtMacr ? imports macros/text messages from a file.
	+ Set Clock ? allows setting of the clock used for file operations. 


* Adds: Serial commands #MAA, #MBA to adjust A or B markers by an
incrementing or decrementing.  The adjustment value is the same as used by
the K3/KX3 UP and DN commands.  Usage: #MAAsn
		s = + to increment, - to decrement 
		n = 0 adjust by 1 Hz
		n = 1   ?   ?  10 Hz
		n = 2   ?   ?  20 Hz
		n = 3   ?   ?  50 Hz
		n = 4   ?   ?  1 kHz
		n = 5   ?   ?  2 kHz
		n = 6   ?   ?  3 kHz  
		n = 7   ?   ?  5 kHz  
		n = 8   ?   ?  100 Hz
		n = 9   ?   ?  200 Hz
Or: 
	#MAAs
		s = + to increment, - to decrement. The step size is automatically
determined by the current span and mode:	
		
USB, LSB, AM & FM 
Span < 5 kHz ? step = 10 Hz
Span 2-9.99 kHz ? step = 20 Hz
Span 10-49.9 kHz ? step = 50 Hz
Span 50-99.1 kHz ? step = 100 Hz
Span 100-200 kHz ? step = 200 Hz
	

CW & Data
Span < 5 kHz ? step = 2 Hz
Span 2-9.99 kHz ? step = 20 Hz
Span 10-49.9 kHz ? step = 50 Hz
Span 50-99.1 kHz ? step = 100 Hz
Span 100-200 kHz ? step = 200 Hz


* Adds: Frequency displays now show all digits including the Hz digit.  This
includes the center frequency adjustment and marker values.  Note that
markers adjust by values determined by the current span setting. 

* Adds: To enter the text decode scratchpad, you can now use either Insert
or Alt-P.  To send the scratchpad, you can now use either Ctrl-Insert or
Ctrl-P . 

* Adds: #MSS msd screen shot serial command. 


As this is a general release, please direct all questions, bugs, etc to
Elecraft Customer Support. 

Kindly, 

Paul N6HZ

I was itching to build another kit so I picked up a K2 kit; It's been enjoyable to see it take shape over the past few weeks.
I even wound up ordering a bunch of the options so I can stretch out the building process a bit more.


I had forgotten how nice of a Kit the K2 was (I built my last one over 10 years ago).

Ken,
When you experienced the mush, did you have the AGC ON, but the RF Gain set
to max, as most people usually do with any other modern radio?  In my
experience, setting RF GAIN max *will cause unacceptable pileup mush in the
K3*, even if you use optimal AGC settings.*
When you can't pull apart a pileup, just back off the RF Gain until some
stations start to stand out.  You can leave the AGC ON all the time.
For reference, here are my preferred AGC and other settings for contesting
with a K3 and large CW pileups.  Others have also reported success with
these.
First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.  Set
CONFIG:TECH MD OFF *when finished*, to eliminate distracting values from
accidentally appearing in the SubRx display (PLL1, AFV, dBV, etc.)
*AF GAIN LO* -- Cuts audio hiss.  May not work with all headphones.  OK on
Heil.*AF LIM 20* -- Only takes affect when AGC is OFF (rarely used)*AGC DCY
Soft* -- Reduces AGC-induced IMD, recommended for pileups*AGC HLD 0.05* --
Slow AGC hold time (50 ms).  Reduces AGC-induced IMD, recommended for
pileups.  Works with AGC-S only, no affect when using AGC-F.*AGC PLS NOR* --
Loud static pulses do not pump AGC*AGC SLP 010*  -- A pretty "flat" AGC
response curve.  I may move this lower since pileups of loud guys can blend
together, but I like this setting because it saves my ears.*AGC THR 010* --
AGC kicks in at about S-8.  Signals lower than THR behave as they would with
AGC OFF ( +1 dB of RF = +1 dB of audio)*AGC -F 120* -- Factory default fast
AGC decay rate (recovery time).  Higher = faster.  Faster can be bad.*AGC -S
20*  -- Factory default slow AGC decay rate (recovery time).  Higher =
faster.  Faster can be bad.*RF GAIN at 3 O'Clock or less* except when all
signals and band noise are very low (e.g. 10m)*AF GAIN* never higher than 3
O'Clock*AFX OFF**NR OFF**NB OFF**RIT OFF**XIT OFF*FL1 to FL5 BW set to match
labeled filter bandwidth exactly, not wider or narrower.Use *AGC-F* or
*AGC-S* for CW, whatever works best for you.Use *AGC-S* for SSB.CW Pitch 500
(or to taste)IF shift centered (on CW)500 Hz InRad 8-pole filter on CW2.8
kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move IF SHIFT
lower for pleasing audio*)Use *XFIL* button to toggle between filters and
reset the IF shift, rather than NOR (hold) button*PREamp ON* for 15m and up,
*PREamp OFF* for all other bands
Hope this helps.

Don makes an excellent point.

I started with a minimal K3 and built it out "under the XYL's 
radar", enjoying it every step of the upgrade path. The second 
receiver was the killer upgrade for trying to work DX with big 
pileups. (I already had the P3.)

The other big advantage of the modular approach is the ability 
to install a improved board in an old radio, bringing it close 
to the latest and greatest. The new synthesizer board is a great example.

Hi Don,

Hold on a second. Up to this point the firmware for the K3 and the K3S has
been exactly the same. The firmware figures out at run time which features
are available whether it being in the K3 or the  K3S and behaves
accordingly. Is there something changed here? That would really complicate
things.

Knut,

The functions of the K3 and K3S are the same, and will likely remain the 
same.  The differences are in the hardware, so a 2nd MCU file has been 
in place for some time to allow for a change in the microcontroller used 
in later K3s and the K3S.
I can envision this being expanded, not to change the functions, but to 
support minor differences in the hardware.  Part of the Elecraft 
"magic", such things are transparent to the user.

My point is that K3Utility sorts it all out, and does not have to be 
visible to the user, because the same steps to update firmware are used.

73,
Don W3FPR

The differences between K3 and K3S firmware features are very minor, all having to do with hardware addressing. For example, the K3S has a second attenuator section. Other than this, there is no difference in functionality.

The reason there are two different .hex files in the load package is that older K3's had a different display controller. This affects so much of the code that I build it two different ways. K3 Utility detects the controller type and loads the associated image.

Bob's a great op, so I really appreciate seeing his settings. But 
they're all run together in his email with no paragraphs or punctuation, 
so it's very hard to read. I copied his settings into a word processor 
and added paragraphs.

-   -   -  -   -   -   -

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set 
CONFIG:TECH MD OFF when finished, to eliminate distracting values from 
accidentally appearing in the SubRx display (PLL1, AFV, dBV, etc.)

*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.

*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)

*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups

*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD, 
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.

*AGC PLS NOR* -- Loud static pulses do not pump AGC

*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower 
since pileups of loud guys can blend together, but I like this setting 
because it saves my ears.

*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave 
as they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

*AGC -F 120* -- Factory default fast AGC decay rate (recovery 
time).Higher = faster.Faster can be bad.

*AGC ?S 20*-- Factory default slow AGC decay rate (recovery time).Higher 
= faster.Faster can be bad.

*RF GAIN at 3 O'Clock or less* except when all signals and band noise 
are very low (e.g. 10m)

*AF GAIN* never higher than 3 O'Clock

*AFX OFF*

*NR OFF*

*NB OFF*

*RIT OFF*

*XIT OFF*


FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider 
or narrower.

Use *AGC-F* or *AGC-S* for CW, whatever works best for you.

Use *AGC-S* for SSB.

CW Pitch 500 (or to taste), IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move 
IF SHIFT lower for pleasing audio*)

Use *XFIL* button to toggle between filters and reset the IF shift, 
rather than NOR (hold) button

*PREamp ON* for 15m and up, *PREamp OFF* for all other bands

Thanks Jim,

I'm new to this reflector, so I'm puzzled by the misformatting.  I made my
post using the web interface (Nabble), carefully formatting the HTML with
the supplied editor.  It looked fine in Preview, and still looks good in
the "View this message in context" HTML link at the bottom of the email,
but it really looks awful in the plain text email.

The problem might be that the reflector doesn't pass HTML, just text.  
I'm not sure about this, but remember reading it somewhere.

That is a very good list to combat crowded band conditions and allow 
copy of weak signals near stronger signals.

For the last few items on that list, you may want to consider 
alternatives for selecting the filters and the use of SHIFT.  It is a 
matter of "operating style" - I know Bob is comfortable with his, but I 
would like to present something a bit different for those not yet 
'ingrained' in their operating habits.

If you use the SHIFT and WIDTH knobs in CW, the filters will change as 
you move the WIDTH knob - this is an alternative to using the XFIL 
button.  Only seldom do you have touch the shift, but it may be handy 
for moving an offending signal out of the passband.  Normally SHIFT 
would be set to your preferred sidetone pitch.

For SSB, tap the SHIFT or WIDTH knob to get the LO CUT/HI Cut LEDs to 
illuminate - then you can narrow the passband with the LO CUT and HI CUT 
knobs - no need to change the SHIFT for pleasing audio, it will happen 
automatically.

You cannot cut the LO end drastically (only up to about 550Hz) before 
the signal intelligibility is affected, but you can cut the HI end 
substantially (down to about 1500Hz) before the signal becomes unreadable.

I find this method much easier than fiddling with the SHIFT in SSB and 
the XFIL button.  I never touch the XFIL button, the filters follow the 
width of the DSP no matter what the mode.

73,
Don W3FPR

Is it possible you need the KPAIO3MDKT?  This cures some issues with electrical fan noise getting into the transmit signal under some conditions after the KSYN3A is installed in all K3 radios and K3S radios before serial (about) 10730.

Could be. I don't have the new synthesizers but the noise is there they say. And just cannot be heard because of the higher phase noise. Maybe my phase noise is low or my fan electrical noise is high.

Thanks for the tip.

Interesting....

That mod is not shown in the Elecraft web pages.  I did the KSYN3A updates in my 
K3 with the sub RX.   How would I know if I need this mod unless someone points 
it out to me on the air? My serial number is in the 5K range.

One of the allures of the Elecraft brand is the ability to keep current.   That 
should not mean just firmware or purchase of major module updates.  I'd like to 
see a mod list for the subtle hardware changes too.   I may not decide to do 
them immediately but would most likely do any the next time the rig is removed 
from its desktop position.

Same goes for other Elecraft gear like the KAT500 and KPA500. For the XG3  there 
was a recent firmware update to it.  As of now I see no need for it but knowing 
it exists I would do it next time I use the XG3.

Hopefully the powers in charge can consider a more complete mod/update 
listing.   Maybe a criterion to make the list could be, "What would the factory 
do?" By that I mean which are important enough for them to do when a piece of 
equipment is returned for repair and updates.

Benny,

I recently had Elecraft replace a KLPA3A again. They also did the Tx IMD mod
and an alignment.
I am now seeing the following 3rd order IMDs:

4W   -40 dBc
8W   -40 dBc
9W   -35 dBc
10W -30 dBc
12W -20 dBc

What is also encouraging is that now the higher order IMDs (5, 7 & 9th) stay
at least 10 dB below the 3rd.
Some of these were equal or higher than the 3rd last summer when I was
discussing the problem with Elecraft. Obviously they have made some notable
improvements since then.
The two tone envelope still looks more like a square wave at 12W, but this
radio is spec'd as a 10W transmitter that is clean to -30 dBc, so it appears
they are now meeting their advertised spec.

I concur with most, but not all, of N6TV's recommendations below.  If we all
agreed on all the CONFIG parameters they wouldn't need to be variable!

One that I particularly disagree with is how to narrow the IF bandwidth in
SSB mode.  The recommendation to narrow the bandwidth and then lower the IF
Shift is unnecessarily cumbersome on SSB.  After going through these
gyrations, you'll find that the LO CUT is where it was before you started.
So, all that needs to be done to narrow the SSB IF bandwidth is simply
decrease HI CUT.  One quick, easy operation and the audio is entirely
intelligible throughout the adjustment.

Bob's a great op, so I really appreciate seeing his settings. But 
they're all run together in his email with no paragraphs or punctuation, 
so it's very hard to read. I copied his settings into a word processor 
and added paragraphs.

73, Jim K9YC

-   -   -  -   -   -   -

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set 
CONFIG:TECH MD OFF when finished, to eliminate distracting values from 
accidentally appearing in the SubRx display (PLL1, AFV, dBV, etc.)

*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.

*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)

*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups

*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD, 
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.

*AGC PLS NOR* -- Loud static pulses do not pump AGC

*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower 
since pileups of loud guys can blend together, but I like this setting 
because it saves my ears.

*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave 
as they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

*AGC -F 120* -- Factory default fast AGC decay rate (recovery 
time).Higher = faster.Faster can be bad.

*AGC -S 20*-- Factory default slow AGC decay rate (recovery time).Higher 
= faster.Faster can be bad.

*RF GAIN at 3 O'Clock or less* except when all signals and band noise 
are very low (e.g. 10m)

*AF GAIN* never higher than 3 O'Clock

*AFX OFF*

*NR OFF*

*NB OFF*

*RIT OFF*

*XIT OFF*


FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider 
or narrower.

Use *AGC-F* or *AGC-S* for CW, whatever works best for you.

Use *AGC-S* for SSB.

CW Pitch 500 (or to taste), IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move 
IF SHIFT lower for pleasing audio*)

Use *XFIL* button to toggle between filters and reset the IF shift, 
rather than NOR (hold) button

*PREamp ON* for 15m and up, *PREamp OFF* for all other bands

My?K2 ZF Adapter came in from QRP-Shop
http://www.qrp-shop.biz/epages/qrp-shop.sf/en_GB/?ViewObjectPath=%2FShops%2Fqrp-shop%2FProducts%2FVk2zfadapter


The manual is in German but they taped each component to a picture of the board layout so it make it simple to assemble.
The Kit with shipping to the US was about $20

Just passing along the info in case someone is looking for one.

I generally run AGC off and the rf gain is never fully open.  I will 
continue to play with settings.

My settings were fairly close but I will try these.

Thanks for the guide!

Subject: [Elecraft] K2 kit ordering

Hi,

So it's time I got on with this, and I can see it happening really soon. 
Before I proceed though I'd like to get an idea about shipping and 
delivery.

The most viable option for me is to have the kit shipped to a UK address 
where I can pick it up on one of my visits so if you are in the UK and 
have experience with K2 kit delivery I'd be interested to hear your 
experience. I'd like to confirm what extra fees are levied on delivery, 
if any. It's likely the kit will be delivered to someone other than 
myself so I want to try and identify for them what might need to be paid 
on receipt.

Many thanks

Martin, HS0ZED

Once you have ordered directly from Elecraft, you will usually receive an 
invoice with the shipping costs added. After you pay, you should receive an 
order confirmation and eventually you will receive a "Package shipped to 
you" email, containing a tracking number. Depending on the over all cost and 
insurance, Elecraft will send via your chosen method of shipping. If it's 
sent by FedEx it will eventually arrive at your chosen destination and will 
have to be signed for. After about 1 week you will receive a written tax 
invoice by post to your shipping address, which will include a fee for FedEx 
collecting the tax on behalf of HMRC. Pay the invoice and you're all done.

If it's sent by USPS they generally hand it over to Parcel Force in Coventry 
and it's held in a customs holding facility until HMRC decide to release it. 
This can sometimes take over 1 week and is very frustrating! Once HMRC 
release your package, Parcel Force will usually take 1-2 days to move it to 
a local depot and in the meantime they will send you a written tax invoice 
by post to your shipping address, which will include a fee for Parcel Force 
collecting the tax on behalf of HMRC. It's probably easiest to pay this 
online with a credit card - full instructions are contained in the 
correspondence. Parcel Force WILL NOT deliver until you pay the tax invoice, 
but when you pay it you can usually arrange a delivery date of your choice.

Taxes: You will have to pay VAT at 20% on the entire package, including the 
shipping charge. Import duty is not charged on Amateur Radio equipment/kits 
etc., Taxes are calculated in GBP.
Elecraft cannot collect international taxes. They must be paid in the 
destination country.

It's generally much cheaper to order direct from Elecraft, rather than a UK 
agent. Although UK agents will receive a lower shipping charge on a bulk 
consignment, they still have to make a profit and they have to charge enough 
extra to cover any warranty they may give. You might have issues with 
warranties from UK agents if you're outside the UK, but it's likely that if 
it's delivered to a UK address and is returned to that same address, they 
would have to honour the warranty. If you're in any way concerned about UK 
warranty, you should call the UK agent and have them give you a commitment 
in writing. AFAIK warranty returns are fairly rare with Elecraft products, 
as long as you follow the instructions when assembling. If you haven't built 
an Elecraft kit before, double read the instructions and take great heed on 
the sections about electrostatic discharge and its prevention.

If you need a UK shipping address, I would be willing to provide it and you 
would have to collect from the Brighton (South Coast) area of the UK. Send 
me a PM if you need this.

73,

Alan. G4GNX

Hi Colin,

Very good point, and idea. But I thought W&S was the UK dealer for 
Elecraft and their website doesn't seem to suggest they carry the K2 range.

Update: A quick look at their downloadable full catalogue dated October 
2016 does list them so I'll send them a mail. Thanks.

73, Martin

Although UK agents will receive a lower shipping charge on a bulk consignment, they still have to make a profit and they have to charge enough extra to cover any warranty they may give. You might have issues with warranties from UK agents if you're outside the UK, but it's likely that if it's delivered to a UK address and is returned to that same address, they would have to honour the warranty. If you're in any way concerned about UK warranty, you should call the UK agent and have them give you a commitment in writing. AFAIK warranty returns are fairly rare with Elecraft products, as long as you follow the instructions when assembling. If you haven't built an Elecraft kit before, double read the instructions and take great heed on the sections about electrostatic discharge and its prevention.

I concur Ed. On SSB when running stations I will only mess with the HI CUT.
Wil crank it down to 2.1. The intelligibility is still good. Sometimes I
forget and just leave it at that setting for the entire contest. It makes it
so you can squeeze in between two other strong stations so that all three
can keep running. Will give it a go again next weekend at KP2M with K3 #311.

I concur with most, but not all, of N6TV's recommendations below.  If we all
agreed on all the CONFIG parameters they wouldn't need to be variable!

One that I particularly disagree with is how to narrow the IF bandwidth in
SSB mode.  The recommendation to narrow the bandwidth and then lower the IF
Shift is unnecessarily cumbersome on SSB.  After going through these
gyrations, you'll find that the LO CUT is where it was before you started.
So, all that needs to be done to narrow the SSB IF bandwidth is simply
decrease HI CUT.  One quick, easy operation and the audio is entirely
intelligible throughout the adjustment.

Bob's a great op, so I really appreciate seeing his settings. But they're
all run together in his email with no paragraphs or punctuation, so it's
very hard to read. I copied his settings into a word processor and added
paragraphs.

-   -   -  -   -   -   -

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set CONFIG:TECH
MD OFF when finished, to eliminate distracting values from accidentally
appearing in the SubRx display (PLL1, AFV, dBV, etc.)

*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.

*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)

*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups

*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD,
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.

*AGC PLS NOR* -- Loud static pulses do not pump AGC

*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower
since pileups of loud guys can blend together, but I like this setting
because it saves my ears.

*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave as
they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

*AGC -F 120* -- Factory default fast AGC decay rate (recovery time).Higher =
faster.Faster can be bad.

*AGC -S 20*-- Factory default slow AGC decay rate (recovery time).Higher =
faster.Faster can be bad.

*RF GAIN at 3 O'Clock or less* except when all signals and band noise are
very low (e.g. 10m)

*AF GAIN* never higher than 3 O'Clock

*AFX OFF*

*NR OFF*

*NB OFF*

*RIT OFF*

*XIT OFF*


FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider or
narrower.

Use *AGC-F* or *AGC-S* for CW, whatever works best for you.

Use *AGC-S* for SSB.

CW Pitch 500 (or to taste), IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move IF
SHIFT lower for pleasing audio*)

Use *XFIL* button to toggle between filters and reset the IF shift, rather
than NOR (hold) button

*PREamp ON* for 15m and up, *PREamp OFF* for all other bands

https://gemsproducts.com/product/kx2-mount/

National Products of Seattle, WA.  The product line is called "RAM 
Mount".  Take a look at this page: 
http://www.rammount.com/products/x-grip.  I don't know if RAM has cup 
holdermounts, but this type of cradle works well.  I use an older 
version of it for my KX3/KX2.

See also http://www.proclipusa.com/ for dash mounts.  I don't know of 
any manufacturer that makes turnkey mount solutions.

Do not try to support your KX2 using only the thumbnuts.  The retainers 
are designed to hold the bottom cover on, not to bear the weight of your 
KX2.

I would suggest that you try to order your options together as well to help cut down on the shipping cost

I'm just finishing up on building my new K2, then it's on to the option kits.

Hi,

So it's time I got on with this, and I can see it happening really soon. 
Before I proceed though I'd like to get an idea about shipping and 
delivery.

The most viable option for me is to have the kit shipped to a UK address 
where I can pick it up on one of my visits so if you are in the UK and 
have experience with K2 kit delivery I'd be interested to hear your 
experience. I'd like to confirm what extra fees are levied on delivery, 
if any. It's likely the kit will be delivered to someone other than 
myself so I want to try and identify for them what might need to be paid 
on receipt.

Many thanks

Martin, HS0ZED

Message-ID: <D28B3579-C468-4438-B566-D0C7606EF3E5@me.com>

I am unable to connect the USB on my K3, modified with a KIO3B set of boards, to my MacMini, running OS10.9.5. I am not able to connect it to my MacbookPro running Sierra, 10.12.3, either. My Macs simply do not see the USB port. If I look at the ?About This Mac? report on the Macs, I see that a ?General Purpose USB Hub? is connected when the USB cable from the K3 to the Apple products is connected. I have made sure I have the latest drivers. I have tried different USB cables. I have Googled and can not find an explanation or a solution. I have done several system resets. Occasionally when I plug the USB cable into the Mini, but not the Pro, I get a message ?USB Devices disabled - please disconnect the device drawing too much power? - doing that seems to do nothing. But I understand the KIO3B draws only 90ma and the Mini puts out 500ma.

Elecraft has told me that they have users who have Macs and KIO3B working.

Has anyone have a suggestion what I should do to fix this? The KIO3B boards were installed by Elecraft so I assume it left the factory working, although I have not ruled out a short or defect in the board that may have occurred
.

I have not tried the K3/board with a Windows computer but the same thing happens when I try to find the ports on Windows10 in Bootcamp.

Thanks in advance for any help.

*Set the CONFIG:RS232 menu parameter to USB. Exit the menu.* ? With the USB
cable plugged in and the K3S turned on, determine which COM or sound device
ports have been assigned to the K3S. This can be done from within
applications. On Windows PCs, an alternative is to locate the Device
Manager (Start > Control Panel > System > Hardware), and view its list of
Ports. When you plug in the USB cable from the K3S, a new COM port will
appear in the list.

If you don't have this item set, the K3 won't recognize the USB connection
and will be expecting a serial port connection. In your MAC look for new
connections after you set CONFIG:RS232 to USB.

If it's already at USB and won't recognize, then you need to call Elecraft
tech support.

Thank you Bill,

You made my day.

When K3s is driving my JUMA PA1000 without 100W PA, the drive is

better than excellent up to 8W.

I need 2W for 600W clean output (-40dB) in SSB.

For CW 4W is enough for a 1000W output (measured with LP100 power meter).

Juma use this active element, and here are some interesting measurements 
for 144MHz:

Benny,

I recently had Elecraft replace a KLPA3A again. They also did the Tx IMD mod
and an alignment.
I am now seeing the following 3rd order IMDs:

4W   -40 dBc
8W   -40 dBc
9W   -35 dBc
10W -30 dBc
12W -20 dBc

What is also encouraging is that now the higher order IMDs (5, 7 & 9th) stay
at least 10 dB below the 3rd.
Some of these were equal or higher than the 3rd last summer when I was
discussing the problem with Elecraft. Obviously they have made some notable
improvements since then.
The two tone envelope still looks more like a square wave at 12W, but this
radio is spec'd as a 10W transmitter that is clean to -30 dBc, so it appears
they are now meeting their advertised spec.

The CODEC is a TI device and it's reporting that 500mA is availableto it, and it's requiring 0mA. The FTDI FT232R UART is likewisereporting 500mA available to it, and it's drawing 90mA. Since the"hub" is inside the KIO3B and being powered by it, it should notbe causing the USB power complaint you're getting on the Mini. BUT,since the Mini is an older device, it is probably USB2, not USB3,and can't source as much current, etc., and its circuitry *may* besomewhat intolerant of sudden changes. (I've had problems with blowingexternally powered USB2 hubs, apparently caused by hot un/plugging,resulting in MacOS reporting devices seen that Parallels and Windowswould/could not talk to. I've now switched to the KIO3B and I'm notgoing to do any hot un/plugging, just to be on the safe side.)
In fact, you might want to see if you can troubleshoot your problemby shutting everything down and powering it all down, configuring yourcabling, and then powering it all back up and booting it up. I knowit sounds like a nuisance, but it may give you a valuable indication.

 Subject: [Elecraft] Can not connect KIO3B USB with my MacMini
   
I am unable to connect the USB on my K3, modified with a KIO3B set of boards, to my MacMini, running OS10.9.5. I am not able to connect it to my MacbookPro running Sierra, 10.12.3, either. My Macs simply do not see the USB port. If I look at the ?About This Mac? report on the Macs, I see that a ?General Purpose USB Hub? is connected when the USB cable from the K3 to the Apple products is connected. I have made sure I have the latest drivers. I have tried different USB cables. I have Googled and can not find an explanation or a solution. I have done several system resets. Occasionally when I plug the USB cable into the Mini, but not the Pro, I get a message ?USB Devices disabled - please disconnect the device drawing too much power? - doing that seems to do nothing. But I understand the KIO3B draws only 90ma and the Mini puts out 500ma.

Elecraft has told me that they have users who have Macs and KIO3B working.

Has anyone have a suggestion what I should do to fix this? The KIO3B boards were installed by Elecraft so I assume it left the factory working, although I have not ruled out a short or defect in the board that may have occurred
.

I have not tried the K3/board with a Windows computer but the same thing happens when I try to find the ports on Windows10 in Bootcamp.

Thanks in advance for any help.

Hi All,

I Just finished my Elecraft K2/10 build.  I have lots of options to add but the basic K2/10 is now working and I'll let it settle in for a week or so to make sure its all ok before adding any options.


I started this build at the end of January, taking care to sort and identify all the parts, especially the fixed value capacitors so it made life much easier to select the correct values efficiently during the build.

Everything went well, got the phase 1 and 2 tests done, added the remainder of the components to finish phase 3 and then when I got to the transmitter alignment step I noticed that rather than about 2 watts out as expected it was over 20 watts!  Gee, what was wrong I thought to myself?  I had a quick look over everything, made 100% sure all the components were installed correctly etc, but couldn't find anything wrong.  I even re-counted all the transformer winding's and made sure they were all installed correctly.  Nothing looked out of place.


Having recently built two K1's and a K2/100 with KAT100 and nearly every option available I knew it had to be something I had done wrong.  So I kept my logic head on and decided after my initial disappointment and re-checking my work that a break away from the bench was a good start.


Back to the bench this morning with a fresh mind I suspected that my issue was somehow with the components that either set or control the power level,  and my reason for thinking that was because the issue was present on every band and the power control pot made no difference to the output power, and RX wise it was performing really well so that eliminated a lot of the sections.  Thinking about ALC or the power control circuit on the control board I decided that was where to start and work outwards from there.  I knew the transmit section of the main RF board was in good shape since it was capable of producing more than 20 watts into a dummy load!


So, I read the circuit diagram, pulled out the control board and started to trace the ALC circuit though the board.. That's when I found my problem, I couldn't believe how stupid I had been and missed soldering pin 2 of RP 3 on the Control Board, which is the ALC feedback loop.  After soldering that and re-testing all was well, phew!!!


Where the lesson was learned was even though I'm close to obsessive compulsive when identifying and selecting each component and double checking twice before soldering anything, then checking with a magnifying glass that the joints look good I still somehow managed to let that un-soldered pin go unnoticed!


I don't think I have caused any adverse effects to the PA section driving it so hard.  The short periods of transmitting at about 23 watts never caused them to heat up.  Its interesting that the PA produced over 20 watts, so the 15 watts max output under normal conditions seems quite a conservative level for those 2SC1969's.


Just thought I'd share my stupid mistake with the readers here and that even being really careful things can still slip through the net!

Glad it turned out well in the end, Cameron. All "solder jockeys" know how a
joint sometimes magically "desolders" itself. 

You were lucky after all. Often the unsoldered joint is making contact with
the thru-plated hole and everything works - until a little oxide builds up
and the resistance climbs until the circuit is open - often months or even
years later. Of course by then a component failure is the prime suspect and
many hours can be lost looking everywhere but the solder joints. 

Enjoy your new K2. I built mine in 2000 and it is still a FB rig.

Yes, you did good. ?One thing I learned when a friend had a project go south and could not find the reason. He brought it to me and it was an enameled wire that he had not striped the enamel off. ?The connection looked good but it did not burn through the enamel. ?Again DETAIL and double checks. ?Now where did I put my keys,,,,,,,

Message-ID: <CAOoYq8_HG3P0eW-5WPHyMY9YdvuK0CpihhCak2Yr=gTev4d8Vw@mail.gmail.com>

Well, the K3S is running, with KPA100 installed.  I have done all the
calibrations suggested.

Two items for now:

No speaker audio, though headphone jacks front and rear work fine.  I tried
the CONFIG:Spkr+PH to minus thing, no change.

Also, trying my Heil Quiet Phone had very low gain - there must be a mike
setting, but I can't think of it.

Tomorrow is sub-receiver installation...

Message-ID: <CAF==Uf18k1MRpakvk5A8t4himhM6WzqXrnPG9SeZ=wR8jGYxUA@mail.gmail.com>

I have Line Out of the K3 connected to Line In on one of my soundcards. The
only way I've been able to record both sides of the QSO is to set the K3
Line Out to PHONES and turn up the MONitor to make it relatively equal in
volume to the received audio. This works, but it's annoying to have the
monitor that high, plus it means the Line Out level follows the AF Gain
control rather than being fixed level.

Is there any way to get both transmit and receive audio mixed on Line Out
at a fixed (and relatively similar) level?

Cameron,

Don't feel bad, it happens to the best of us.  I am glad you found the 
problem.

Be careful to make certain pin 1 of the ICs and Rpaks is soldered.  The 
solder pad for pin 1 is a different shape than all the rest, and is 
often missed by builders.

Congratulations on your troubleshooting skills.  Good luck as you add 
the options.

Contrary to what Heil recommends, set the mic gain range to high for 
those low output Heil microphones.

For the speaker audio, I suggest you contact K3support and they may be 
able to guide you though some tests.

Many moons ago when there was a K2 but no KPA100 I wanted to drive an 
amp with my K2 and I needed a few more watts. I made some modification 
(I don't remember the details) that allowed it to produce more than 20 
watts, which made a big difference in output from my amp. I operated for 
a while like that until the KPA100 came out, and it didn't seem to hurt 
anything.

On the speaker topic, please check your  Owner's Manual Errata
<http://www.elecraft.com/manual/E740258E%20K3S%20Owner's%20man%20errata%20A1-2.pdf>  
- 2nd item.

Agreed with Don on the mic input.  Also, please be sure to read the section
in the Owner's Manual about how to set proper mic audio drive levels - it is
different from other radios.

Cheers,

David/KG6IRW

The problem of no TX Monitor audio on LINE OUT was fixed last July, in MCU
firmware 5.51, DSP 2.88.

What version of firmware is your K3 running?

I have Line Out of the K3 connected to Line In on one of my soundcards. The
only way I've been able to record both sides of the QSO is to set the K3
Line Out to PHONES and turn up the MONitor to make it relatively equal in
volume to the received audio. This works, but it's annoying to have the
monitor that high, plus it means the Line Out level follows the AF Gain
control rather than being fixed level.

Is there any way to get both transmit and receive audio mixed on Line Out
at a fixed (and relatively similar) level?

Which speaker doesn't work, the internal speaker or an external one plugged
into the SPKRS jack on the back?

If internal, did you remember to connect the 2-pin cable to the header
before putting the top cover on?

If external, did you use a stereo plug or a mono plug?  If mono, did you
set CONFIG:SPKRS to 1?

Re. mic gain, there's a SPEED / MIC knob on the front of the radio.  Did
you turn it?

What type of Heil mic do you have, dynamic or electret?  From the K3 manual:

MIC

MONO; hi- or low-Z

"This jack accommodates an electret or dynamic
mic. Use MAIN:MIC SEL to select the rear panel
mic (RP). Tap 1 to turn on Low or High mic gain
range. Tap 2 to turn bias on/off (see pg. 28 for
recommendations based on mic type).

"For the front-panel mic only, additional microphone
gain can be enabled by tapping 3 . Use this only for
very low-output mics."

Well, the K3S is running, with KPA100 installed.  I have done all the

Two items for now:

No speaker audio, though headphone jacks front and rear work fine.  I tried
the CONFIG:Spkr+PH to minus thing, no change.

Also, trying my Heil Quiet Phone had very low gain - there must be a mike
setting, but I can't think of it.

Tomorrow is sub-receiver installation...

In playing with Bob N6TV's suggested settings, I've discovered that on CW,
neither the Shift->LO Cut nor the Width->HI Cut controls change functions
when tapped.  They appear fixed at SHIFT and WIDTH.  Tapping them merely
displays their current setting.  On SSB, they change and work as expected.
Is there a parameter setting somewhere that affects this?  I've looked
through the release notes but see nothing.

Using the latest firmware: 5.57

Bob's a great op, so I really appreciate seeing his settings. But they're
all run together in his email with no paragraphs or punctuation, so it's
very hard to read. I copied his settings into a word processor and added
paragraphs.

-   -   -  -   -   -   -

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set CONFIG:TECH
MD OFF when finished, to eliminate distracting values from accidentally
appearing in the SubRx display (PLL1, AFV, dBV, etc.)

*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.

*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)

*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups

*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD,
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.

*AGC PLS NOR* -- Loud static pulses do not pump AGC

*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower
since pileups of loud guys can blend together, but I like this setting
because it saves my ears.

*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave as
they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

*AGC -F 120* -- Factory default fast AGC decay rate (recovery time).Higher =
faster.Faster can be bad.

*AGC -S 20*-- Factory default slow AGC decay rate (recovery time).Higher =
faster.Faster can be bad.

*RF GAIN at 3 O'Clock or less* except when all signals and band noise are
very low (e.g. 10m)

*AF GAIN* never higher than 3 O'Clock

*AFX OFF*

*NR OFF*

*NB OFF*

*RIT OFF*

*XIT OFF*


FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider or
narrower.

Use *AGC-F* or *AGC-S* for CW, whatever works best for you.

Use *AGC-S* for SSB.

CW Pitch 500 (or to taste), IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move IF
SHIFT lower for pleasing audio*)

Use *XFIL* button to toggle between filters and reset the IF shift, rather
than NOR (hold) button

*PREamp ON* for 15m and up, *PREamp OFF* for all other bands

Subject: [Elecraft] K3 Remoterig K3/0 MIC connection
Message-ID: <1488122016390-7627375.post@n2.nabble.com>

Hello,

I have a problem connecting a Heil headset to the K3/0-mini.
Guess it is a configuration problem, since it works OK if conneced directly
to the K3 in local mode.

I have tested it with the K3 MIC set to "rP.H bIAS" and K3/0 to "FP.H bIAS"
(configured when K3/0 was disconnected from Remoterig).

Can't find anything about this in the K3-Remote manual.
Could someone point me to the correct setup of both the K3 and the
K3/0-mini?
Any help is most welcome.

73,

Per-Tore
LA7NO

I just found tha there is a comment on the K3 mic setting on the top of p.16
in the K3 Remote manual.
I have now changed my setting for K3 to "rPL". Not sure if it should have
been "rPH".

Does the setting of the K3/0 have any influence when in remote  mode?
I find it a bit confusing that there apparently are two menu settings for
the K3/0:
one while disconnected from Remoterig and another while connected through to
K3.

P-T

When the K3/0 is connected to the K3, the rP or Fp menu sets the condition
of the K3, not the K3/0.
When the K3/0 is not connected, the setting changes the K3/0.
But I have had much better luck with connecting directly to the mic input om
the RRC control, so try that if you can.

I just found tha there is a comment on the K3 mic setting on the top of p.16
in the K3 Remote manual.
I have now changed my setting for K3 to "rPL". Not sure if it should have
been "rPH".

Does the setting of the K3/0 have any influence when in remote  mode?
I find it a bit confusing that there apparently are two menu settings for
the K3/0:
one while disconnected from Remoterig and another while connected through to
K3.

Subject: [Elecraft] Sub-RX no signals
Message-ID: <CAOoYq8_tBaXbZYXzqM4hVvStoBgTK5SR3NdPOSRw0_iU3D7thQ@mail.gmail.com>

Well, the Sub receiver was installed this morning, filters and config
seemed to complete without problem.

However, the Sub-RX does not seem to be getting any signals.  I see the
Ant=Main when I use B-Set, so it should be sharing the main antenna.

Any suggestions?  Nothing pops out on the CONFIG list, and I had three TMP
cables plugged into the SubRX module, there were only 3 jacks I saw.  There
were no unplugged ends inside the case.  There was one leftover TMP
cable... I thought it was for the 144 module I don't have.  I may have to
open it up and re-check all the TMP cables.  Unless it's a simpler fix.

Thanks, John. This fits with what I have assumed.

I would like to try connecting the mic directly to the RRC-control, but I do
not have the reqired adapter.

We'll see...

Never mind...

Walked back through the setup and realized I hadn't set the installed SubRX
filters on all modes... just CW.

All seems fine with the SubRX now.

If CONFIG:PB CTRL is set to .01 in CW mode, then, per the function 
description in the K3 Owners Manual (pp. 62 in Manual Revision A1), you 
will be limited to the Shift/Width controls mode only. Change PB CTRL to 
.05 and you will also enable LO/HI cut on the controls.

Chuck,

Looks like your reply didn't go to the list, so I'm quoting it below for
the benefit of other readers.

It looks like KG6IRW has the solution.  From the Owner's Manual Errata:

"IF THE SPEAKER IS NOT WORKING with headphones unplugged: Locate the
CONFIG:SPKR+PH menu entry. Tap ?1? on the numeric keypad until you see PH.R
SW?. The minus sign (-) indicates inverted switch logic for the jack on the
KIO3B audio board. Exit the menu and re-save your configuration using K3
Utility."

If like me you are rather horrified to find that the Li-ion charger and

I've just found one of these adapters which replaces the cable completely.
No doubt similar adapters exist for other mains plug designs.

It started behaving erratically , it either does not react to the RF input
, or if it does then never finds the tune ending up with the red LED on.
It is not related with the antenna type,  it is all the same even with the
perfectly tuned R-8 on. The self LC test procedure as described in the
manual , though went ok. Disconnecting and re-connecting the battery doesn'
help. I also tried to eject and reinstal the microprocessor chip to no
avail. Visual inspection of the boards brought nothing suspicious and
resoldering the BNC contacts hasn't made any difference.

Any wise advise is welcome ! ( Except the " send it back to Elecraft" type,
:). It would be cheaper just to order the new one, :)

If f.ex. both K3 and K3/0 has the tx equalizer set, will their effect be
added?

Can it be the Remoterig settings are incorrect?

Linas,

It sounds like a microprocessor problem, but I can't be sure.
Do you know of any locals who also has a T1 and would be willing to try 
swapping the microprocessor?

It may be heplful to contact Elecraft support even though you may not 
want to send it in for repair.

Don, Jim, thanks.
Could be a processor, agree. Paradoxically, I have excactly  the same
problem with the big MFJ-927 tuner and the preprogrammed chip replacement
from the company made no cure, :).
The buttons seems like working for they do switching during the test mode.
 I'll definetely write to the Electaft tech support, they are quick and
friendly, once have helped me a lot by guiding through the fix of the K3
I/O
board.

 Re:? " I have excactly (sic)? the same problem with the big MFJ-927 tuner and the preprogrammed chip replacement from the company made no cure"

No, wait, what???? You have the same problem with a tuner make by a different manufacturer??? It is time to start looking for items that are in your system no matter which tuner or antenna you are using.? Don't ignore the radio side of the tuner.? An intermittent short or open in a connector or coax on the INPUT side of the tuner will cause the tuner to be unable to figure out what frequency you are on since it can generate square waves with harmonics well above HF.? Look for items that are common no matter which tuner you are using, and don't forget the radio itself.

Message-ID: <CANksMQ_-gPusd8bG2t0fY2VMVRuEjE32EWk31E5dEjNF0Ppk8A@mail.gmail.com>

Finished my K2 in the last few days and really enjoyed the build. It was
just like old times.

All bands except 12m have aligned OK...but I cannot get any more than .5W
output on 12m - no matter the C44/46 trimmer cap settings or the power
setting. And while it not fun, I pulled components C42,C43,C44,C45,C46,C47
and C48 and they all showed fine on the cap tester. C32 and C34 are
adjustable from about 35pf to 70pf.

I measured RF voltages. All transmit stages were fine up until the bandpass
filter. Zero RF volts at W6 and the anode side of D1. One thing I have seen
on keydown is the RF on both sides of C48 jumping to about .4V RF, then
right back to 0. Cap C42, on the other hand shows well over 1V RF on
keydown.

Because 10m is aligning/peaking totally fine and putting out 14W, and the
caps and inductors test good, at this point should I assume K7 isn't
swithing? I am not really sure of the best way to test K7 in place. Any
tips would be most appreciated. :-)

The K3 Owners Manual is up to revision D10 dated 8/24/2011 with errata
D10-8 dated 3/31/2015.

Seeing as both are PDF's and fully searchable, probably need to be current
as opposed to something dated back in 2007. Only 8 years out of date.

However, the warning you quoted is still in the newer text.

For myself, not being able to do 10 Hz shift is an issue for CW and the
very steep skirts using a roofing filter with DSP width set to the roofer
width. If the guy up or down gets a little too loud, just a dime Hz shift
or two or three will drop him right out. 50 Hz is way too coarse for that.

Also for normal QSK (not the one which turns on the display +), which *is*
very good with the new synthesizers, I do NOT lose RIT or XIT in QSK. With
the new syns regular QSK is more than adequate to hear between dits or
letters at 30 wpm on the RX antenna.

This is in spite of my having the Microham box and it's built-in WinKey
functions set for unbroken PTT assert to the Alpha 8410 on the TX antenna
until a word space has gone by. The K3 can't do RX/TX one way and it's PTT
out another.

So what I have is the very best of the fast and the very best of the slow
at the same time. I only hear in the right ear on the subRX when the 8410
is keyed, and I hear in between the dits. This allows me to hear when
someone calls late, just a bit after I start calling CQ again on a run.

Best of the fast.

But even though the K3 is cycling TX/RX very fast the 8410 is not banging
the vacuum relay to death trying to follow 30 wpm dits. 30 wpm QSK *does*
significantly shorten relay time to failure. Contesting, I've worn some out
in less than a year.

So to save me that, the Microham box keys up the amp with it's PTT before
it starts the key sequence to the K3. That's because *both* the paddle and
the PC logging program stream go to the Microham box which in turn keys the
K3. I also have inverted the Microham PTT keying to control 12 volt supply
to protect some sensitive stuff, better off not powered during TX.

Best of the slow.

Gotta say, if you don't have the new syns in your K3, that is an absolute
top-run improvement.

Bob,

You have too much capacitance at C32 and C34.

Contact Elecraft support and ask them to send 2 trimmer caps to replace 
C44 and C46.  The ones you have with your kit do not have a small enough 
minimum capacitance.  The p/n you need is E540011 and the bodies were 
red the last time I saw them.

The 35 to 70pF range you measured is higher than I would expect.  They 
should measure about 20pF to 45pF.

If you have a similar problem with the maximum power on 18 MHz as well, 
ask for replacements for C32 and C34.  The part number is E540002 and 
they have yellow bodies.

See the latest Errata page - download it from the Elecraft website.
Trimmer capacitors have become a problem for Elecraft over the past 6 
months or so.  I believe you have brown body trimmers at C32, C34, C44 
and C46.  Several of those were found not to meet the manufacturer's 
specs for capacitance range and were dropped.

Don W3FPR

Indeed, I have the brown trimmers at C32/C34 as well as C44/C46. The latest
errata sheet from Nov 2016 says C44/C46 should have red bodies and be about
25pf. The ones I have do not go below low-30pf. Thanks for the help, Don!

i see people confusing Lipo with LifePo4

two different chemistries.

would you not agree that one benefit of Lipo 14.6 batteries is their voltage
being above the 13.8 spec?

Tom,

Consider cost vs. need and your intended power level.
If you are backpacking in, then weight is a consideration, so LiPo and
LiFePO4 batteries are to be preferred.  IMHO, LiFePo4 are preferred because
they have terminal voltages similar to NiMH ot NiCad batteries and the
charging requirements are not as severe (and safety oriented) as LiPo.  LiPo
batteries need special chargers to insure safety during charging.

If you don't mind the weight of lead acid batteries, then the low cost
alternative is a "lawn mower" battery, or if spillage of the electrolyte
might be a problem, look at AGM or SLA batteries. That is old battery
technology, but it works and is the lesser expensive solution.

An almost zero cost solution is to run heavy gauge wires from your vehicle
battery.  Just make sure there is enough energy left to start your vehicle
when you are ready to break camp.

Bob, Don,
I just finished up a K2 as well.? The trimmers I got didn't match the description in either the manual or errata, so I wasn't sure what I was looking at.
I had to use clip leads from my cap meter and got too much stray stuff going on to accurately measure min and max.
I talked to Gary in Watsonville.? Here's what we summized.? The larger bodied yellow trimmers went into c21 and c23.? The remaining 4 smaller bodied white with red band trimmers went into c32, c34, c44 and c46.
It works.? I get good output on all bands.
Don't know if this helps or not.

Bob,

You have too much capacitance at C32 and C34.

Contact Elecraft support and ask them to send 2 trimmer caps to replace 
C44 and C46.? The ones you have with your kit do not have a small enough 
minimum capacitance.? The p/n you need is E540011 and the bodies were 
red the last time I saw them.

The 35 to 70pF range you measured is higher than I would expect.? They 
should measure about 20pF to 45pF.

If you have a similar problem with the maximum power on 18 MHz as well, 
ask for replacements for C32 and C34.? The part number is E540002 and 
they have yellow bodies.

See the latest Errata page - download it from the Elecraft website.
Trimmer capacitors have become a problem for Elecraft over the past 6

Thanks Bob, that was it (I was at MCU 5.50). Updated to latest and changed
LIN OUT back to NOR, and it works exactly how I wanted.  I also found a
powerpoint presentation out on the web that you did for CTU on the subject
of recording contest audio - very informative.  Thanks!  Guess I need to
make more of an effort to watch for firmware updates- this radio keeps
getting better and better.

Chuck,

WHAT??  Did you have 4 ceramic trimmers with red dots on the side?  The 
same as that used for C22 on the Control Board?  Those normally will not 
work for the 12 meter bandpass at C44 and C46.

The large yellow plastic trimmers should go at C32 and C34, and the 
ceramic trimmers with the red dot should be at C21 and C23.
There is not a great deal of difference between the ceramic trimmers 
with the red dots and the plastic trimmers with the yellow bodies, but 
in extreme cases, the difference is enough to cause a problem tuning 14 
MHz and 18MHz.
You should have had 2 red bodied trimmers similar to the ones with the 
yellow body, and those would go into the C44 and C46 positions.

If the trimmer capacitor selection has been changed, then the K2 errata 
page must change to keep up with it, and it apparently has not.

I will contact the K2 product manager to see what is going on.

I would think it would be best to use:
The Yellow (ones 6.8-45pf) at ?C44 & C46 (10/12 m) since the schematic calls for 5-30pf
The White with Red dot ceramic trimmers (8-50 pf) at C19 and C23 (20/30m) since the schematic calls for a 50pf trimmer

C32 and C34 should also be 5-30 as per the schematic, so a better substitute would seem to be to use the Yellow 6.8-45 pf trimmers

I went through the same business with my first K2, apparently during the switch-over of trimmer suppliers.  None of the colors matched what they were supposed to be and the errata sheets didn?t help at all.  Don Wilhelm and Gary Surrency both went out of their way to help me sort it out.  

Although my DVM is theoretically able to measure capacitance, the long leads make it essentially useless.  So when I ordered my second K2, while I was waiting for it to arrive I put together a very inexpensive capacitance tester that sold for about $10.  It has PCB mounted test points that work with no leads at all, and the spacing is perfect for these little trimmers.  I then tested what I received in the second K2 kit before mounting them, found that there were still questions, and once again Elecraft came almost instantly to my aid.  But at least I didn?t have to undo anything, or puzzle about why something wasn?t working right.

Sounds as if the K2 trimmer supply is a recurring problem.  Using the capacitance tester before mounting them saved me a great deal of trouble.  Having bought it, I now test EVERY cap before installing.  Takes a while, but it?s reassuring.

There are lots of inexpensive testers available on the ?Net.  I think this is the one I bought:  http://www.nkcelectronics.com/capacitance-meter-kit.html.

    Bob,
    
    You have too much capacitance at C32 and C34.
    
    Contact Elecraft support and ask them to send 2 trimmer caps to replace 
    C44 and C46.? The ones you have with your kit do not have a small enough 
    minimum capacitance.? The p/n you need is E540011 and the bodies were 
    red the last time I saw them.
    
    The 35 to 70pF range you measured is higher than I would expect.? They 
    should measure about 20pF to 45pF.
    
    If you have a similar problem with the maximum power on 18 MHz as well, 
    ask for replacements for C32 and C34.? The part number is E540002 and 
    they have yellow bodies.
    
    See the latest Errata page - download it from the Elecraft website.
    Trimmer capacitors have become a problem for Elecraft over the past 6 
    months or so.? I believe you have brown body trimmers at C32, C34, C44 
    and C46.? Several of those were found not to meet the manufacturer's 
    specs for capacitance range and were dropped.

I listened to check in to the 40 meter net. I could faintly hear the net
control station but could not copy his transmissions here in Washington
State.  Most California stations were at least 5 7 or 5 9 but I didn't hear
anyone ask for relays to check in.

I thought the errata sheet was up to date. We'll look into this tomorrow.

So when I ordered my second K2, while I was waiting for it to arrive I put together a very inexpensive capacitance tester that sold for about $10.

Harry,

The yellow ones do not go reliably down to 6.8pF, many are limited to a 
minimum capacity of about 15pF.

The capacity for the 12 meter bandpass needs to be in the 11 to 12pF 
range or less.

Yes, I have measured several of them.  I went through this as the tester 
for Elecraft when the wide range blue trimmers were no longer available.

The current ceramic trimmers (white with red dot) do not reliably go 
down to 5pF - the minimum is more like 12 to 15.  The old blue trimmer 
capacitors had a reliable range of 5 to 40pF and were ideal, but alas, 
they are not longer available.

This thing with trimmer capacitors is turning into a 'bag of worms'.

73,
Don W3FPR

Yes Don.? They sent me 4 trimmers that look identical to c22 on the control board.
No red body trimmers.

Chuck,

WHAT??? Did you have 4 ceramic trimmers with red dots on the side?? The 
same as that used for C22 on the Control Board?? Those normally will not 
work for the 12 meter bandpass at C44 and C46.

The large yellow plastic trimmers should go at C32 and C34, and the 
ceramic trimmers with the red dot should be at C21 and C23.
There is not a great deal of difference between the ceramic trimmers 
with the red dots and the plastic trimmers with the yellow bodies, but 
in extreme cases, the difference is enough to cause a problem tuning 14 
MHz and 18MHz.
You should have had 2 red bodied trimmers similar to the ones with the 
yellow body, and those would go into the C44 and C46 positions.

If the trimmer capacitor selection has been changed, then the K2 errata 
page must change to keep up with it, and it apparently has not.

I will contact the K2 product manager to see what is going on.

Don W3FPR

When you hear the others sending their call or "hail" sign just send 
yours.  Usually I'll get alerted to you by the other ops. Today I was 
getting comments about how folks were hearing which did not match what I 
was hearing.  I was in the middle of a torrent of rain from my trees.  
The sun was hitting the new fallen snow and melting it.   My normally 
strong path to the Anchorage, AK area was not there as well the one into 
MI.  Forty meters usually captures all of WA and some of OR.  I did work 
one Portland, OR station which is normally out of my reach because of 
the mountains in the way.

So send your call sign when you hear the others send theirs. Then they 
will feel guilty for not telling me if they read more of these email 
messages.  Guilt worked for my parents I think this is the perfect spot

Hello all,

I want to know if someone here is using the DigiMaster Pro and If I could
get some advice on how to do the right audio cables myself so to be able to
use it with WSJT-X. I've got already the CAT one. This is the interface:

http://www.g4zlp.co.uk/unified/DM_PRO_PLUS_complete.shtml

Is there a simple way to workout the Tx (mic out) from my laptop into the
KX3? I can already control the radio via CAT but i'm kind of lost as on
what to do with sound cables.

TIA

I have some 3 cell LiPo batteries normally used for RC aero models and I'd
like to try these externally with my K2. The batteries are 3.7V per cell
500mAH which will give 11.21 V fully charged.
I do of course have a suitable charger for LiPo batteries.

How will the K2 perform at this reduced voltage? Opinions please.

Deni,

It should work fine, especially if you keep the power to 5 watts or 
under.  Set the CAL CUR parameter at 3.50 Amps to avoid HI CUR warnings.

If you try to run at 10 watts, the IMD will be reduced and the current 
draw will be excessive.

Remember that the K2 tries to produce the power requested by the POWER 
knob, and in order to maintain that power at reduced voltage, the 
current must increase.

Hello group,

I have noticed that the settings of AF and RF gain is taken from the actual
settings of the K3 that is being connected to.
If the K3/0-mini has different settings, these come into effect by just a
very slight twist of these controls.
I would expect that the K3/0-mini settings should be used, since it is here
the operator is.

Can it be that this also goes for other settings?

Hmmm...

What about the mic connector on the side of the K3/0-mini?
Is this in parallel to the main connector? Or how is it selected?

I have been thinking of purchasing a 7300 as a backup to my K3 
(non-updated) and am wondering if anyone has done a real side-by-side 
comparison of the two radios??

Of course I could purchase a new K3S and keep the K3 as the backup. 
However, for my daily use of ham radio, I am not sure that would be the 
best approach for me.

I normally only operate on 40 and 75 meters on nets and rag chew. My 
station (speakers, antennas, etc.) is designed for armchair copy 
reception. To that end, the K3 does an excellent job.

So, if you have experience using both radios, I would sure like to hear 
from you. You may either post here, or contact me directly at 
w2blc.nycap.rr.com.

Thanks,

Bill W2BLC K-Line

ARRL reviews most new rigs, but I don't see one for the 7300.

http://www.arrl.org/reviews-listed-by-manufacturer

For the way you operate, If I were looking for a lower cost backup for a 
K3, I'd look at something like the TS590SG. A friend who's a great 
operator owns one and likes it, and ARRL lab test data for it is quite 
good considering its price.

Bill,
If you are interested I have a Kenwood 590 S with a digimaster for sale as
I have recently purchased K3S and KX2 and do not have a need for more
radios. I do not want to do sales on the forum, so if interested contact me
directly. Have had great results with 590S and 590SG, but there are other
good rigs out there these days as well

Today is a good day to have a Great Day!

Right.

Yes, but LiFePO4 are a better choice for most ham applications. They are 
a safer battery, and the discharge curve of a nominal 14.2V pack stays 
above 13V for most of its capacity, as compared to lead-acid chemistry, 
which stays below 12V for most of their capacity.   Here are two good US 
vendors. The second one, Battery Space, also sells a broad range of Li 
Ion batteries. Both vendors have good people to talk to on the phone and 
via email. Bioenno has been exhibiting at hamfests, and their products 
are sold by Ham Radio Outlet. I've made them aware of the RFI issues 
associated with their chargers, and they are working on finding suitable 
replacements.

With a nod to Cool Hand Luke

I have mentioned this before in another thread but have heard no response.

I, and I know others, have experienced the annoyance of tapping a key on the 
K-Pod and after noticeable latency, seeing a message appear in the VFO B space 
that acknowledges the tap, yet the requested action fails to occur.   
Specifically in my case, I'm trying to send CW messages stored in M1-M4.

This use was the main reason I asked for one of these for a Christmas gift, so I 
could use my left hand and save both the buttons on the radio and/or my rotator 
cuff on my sending hand.

Can we get a fix for this?

Wes  N7WS

ps. Another function button is supposed to turn VOX on and off. This fails too 
often as well.

The current Sherwood Engineering receiver test data list includes all of these radios.

In the latest figures, the K3 (old synthesizer) rates above both the 7300 and TS590G.  The 7300 is down 5 in the list from the K2 and the 7300 is two above the TS590G.

If you just installed the upgraded synthesizer you would improve your K3 by five spots.  In fact, only the full K3S and Flexradio 6700 are currently better.

However, for casual rag chewing I would think any of these transceivers would be just fine.   It would be a matter of personal preference.  I know several people who are very happy with the TS590G.

These are all quality rigs.

?I'm going to second the Bioenno solution. I use the BLF-1215W and it kept
my KX3 running through Field Day last year along with some other shorter
term field events. I often run the KX3 at 3 watts when portable with
intermittent forays into 5+ watts when deemed necessary.

I have not had any issues with RFI from their charger but, and I believe
this is common, what is quiet for some is noisy for others. Maybe the RFI
issues Jim reported has already been addressed? One thing I've been warned
about... LiFePO4 batteries have special charging requirements. Not any ole
charger will do.

Apparently the list is out of date -- KK7P emailed me that the 7300 was

Hi Folks
Quick question for you.

I have a KX3 (three) and a KX2 (two) and a KXPA100.

The kx3 and pa100 work fine.

However, when I use the kx2 it isnt fine.  I set AUX2 to ON, PA to ON and
all is well UNTIL I go over 10 watts.  When I go above ten watts on the
dial setting on the kx2 the TX light on the PA comes on and of course my Rx
goes deaf.  Wind it back to below 10 watts or below and the relay in the PA
clicks and the Rx works again.

Ive got latest firmware in KX2 and PA100.


What am I missing?

Keep in mind that the Sherwood rankings are based on 3rd Order Dynamic Range at 2 Khz spacing ? not on any other factor, and not on some general measure of a radio?s ?goodness?.   While it isn?t necessarily unimportant even for casual rag chewing, it may not be the most important consideration.

Have you tried programming the identical function into both the TAP and
HOLD macros for each button?  It's very easy to hold down a K-POD button a
bit too long, which runs a different macro.  If nothing is programmed for
the HOLD function, you'll see "MACRO 1" or similar blink in the VFO B
display.

If that's not it, what are the command strings programmed into M1-M4?  Do
they contain any leading or trailing blanks?

I have had both the IC-7300 and the K3S here in the shack as well as the
TS-590SG.  The IC-7300 has it's little nice features but I didnt find it
better than the TS-590SG for rag chewing and general use. I have an IC-7600
and I found that the IC-7300 didnt really have as good sounding a
receiver.  For my $$$ I would purchase the Kenwood TS-590SG for a backup to
my K3S if I didnt already have an IC-7600.

Just my opinion, YMMV.

I ran my K2/10 and K1 from my RC batteries for years. Mine were only 2000mAH. When they started sagging for RC, I used them for the radios where peak current draw was dramatically lower. I ran the rigs at 5 watts as Don mentioned. The signal was clean and at that power level they would barely tax the batteries over an entire weekend in the field.

David,

I don't know the KX2 well enough to give you even a guess, although it 
is obvious that something is putting the KXPA100 into transmit.  Do you 
have the ACC plug fully inserted - give it that extra bit of push.

But something is apparently wrong, and I suggest you contact K3support 
at Elecraft.

I spent some time with the Icom ic-7300 last fall at the HRO in Portland Oregon (actually, Tigard).  I was impressed with the layout, features available on front panel, touch screen and overall size.  It was smaller than I thought it would be (from a former Pro III owner) and even though a touch screen is no where near the top of any wish list of mine, it seemed to work well and offer the most obvious features via touch.

For awhile there I was thinking why not ? why not add this cute little SDR to my collection.  Then I realized that it would mostly collect dust or some other radio would collect more dust and besides, I would probably rather spend the money on some more woodworking equipment.

But, if you need a good backup radio, this one is priced right and probably would not be a mistake.

I own the K-3 and have recently purchased the IC-7300. If you use the P-3 Panadapter, with your K-3 then you will not be happy with another rig that doesn't have a band-scope. I like the IC-7300 very much.

I had that problem manifest itself on my KX3/KXPA100 system.

Double check that both ends of the KX3 to KXPA100 adapter cable (that little black box that is connected to the PA100 via the RJ45 connector) are completely mated/pushed in where they are inserted in the ACC1 and ACC2 jacks on the KX3...

Message-ID: <CABBJzNinvHqirVZozh0X4Py4cXaO5CpzXHU-=Ntpb-QBDsBa1g@mail.gmail.com>

Let me see if I can explain this.  I have two speakers hooked up to my K3s
using the appropriate adapter and have them working fine.   I can hear each
receiver in a different ear and the AFX function works.  I have a set of
Heil headsets that also work the same as the regular speaker.

I acquired a wireless headset that plugs directly into the mic input and
phone output.  The headsets were originally designed for telephone call
center use so they are monaural only.  I can plug them into either the
front phone jack or the rear phone jack and I hear the audio just fine.  I
have the Config:Spkrs set to 2 since I have to regular speakers and a Heil
headset that I often monitor and enjoy the AFX and the separate receive
audio.  The wireless headset audio is wired with a stereo plug but no
connection to the ring.

The plan would be to plug the wireless headset into the rear of the radio
and either the heil headset or a hand microphone into the front.

I read all the warnings about how to connect speakers and headphones.  So
is there any harm in connecting the wireless headset(remember it is
monoral) to the phone jack using a stereo plug and keeping Config:Spkrs 2?

Well, my operation is similar to yours in that I don't do contests and work
DX only if I happen to stumble onto it.

That said, I think the IC-7300 would be more "fun".
I own both and while the K3S will probably out-perform the Icom, the '7300
has more bells and whistles.
I'm not the one to ask for actual performance comparison but I AM a bell &
whistles type and appreciate the fun stuff the Icom will provide.

For starters, a color display spectrum AND waterfall which is miles ahead of
ANY built-in scope display I've ever seen with the possible exception of the
one in the IC-7851.
My opinion is that it is as good as the P3 although not quite as versatile.
However, I rarely look at the P3 itself since I drive an old 15" computer
monitor for that.

When you mention AUX2, it suggests to me that you're trying to key the amp by directly connecting the KXPA100 PA KEY port to the KX2's AUX jack, which is not the same as the KX3's ACC2 jack.?

Could you clarify how your KX2 is connected to the KXPA100? Are you using the recommended method of connection, i.e., the KX2ACBL and KXPACBL adapters? My intuition is that the KX2ACBL is the most likely culprit; either it isn't fully seated, or it isn't there.?

Message-ID: <d7d514e6-aeac-54a3-fca6-0e4880607f0a@gmail.com>

I use the K3 (entire K line) at home most of the time (the BEST radio 
I've ever used and the integration is beyond compare).  I'm very used to 
the controls having moved from the Kenwood TS-940; they're VERY similar 
and it was a shallow learning curve.  I wanted a portable, RV and FD 
radio and considered another K3 by moving my K3 parts into a K3S.  I 
didn't want a huge budget since that radio wouldn't be used enough to 
justify a large expense.

I went with the IC-7300 (now less expensive).  It's small, has many of 
the features I use on the K3 (bandscope being the main one) and with the 
AH-4 tuner means I can be on the air with almost any wire, quickly.  
That combination was less than a K3 and added the 'scope.  It's also 
light (a huge consideration for RV life). It also caused me to learn 
about battery technology so I now power it with LiFePo4 batteries 
instead of using the RV house battery (which also means I don't have to 
hunker indoors).

In use, it's sensitive, easy to use but it's 'different' from the K3 (I 
likely need to spend more hours on the Icom but haven't; it's not 
intuitive to me).   The Icom has some of the controls (like keyer speed) 
hidden in touch menus instead of on the front panel (where they belong, 
like the Elecraft folks figured out). It's a different mindset since I'm 
not a long time Icom user.  The touch screen is nice; the scope works 
fine once set, but you also can't save the settings per band or mode; 
it's rather limited compared to the P3 (touch and QSY is nice, but never 
ON the exact freq you want).  If you have fat fingers, you'll be 
frustrated with the touch screen.

The '7300 lacks a couple (what I would consider basic) connections.  
There is only ONE antenna port (anyone have a 160-6M antenna?), there is 
no video output of the scope (so I don't have to squint), in fact there 
aren't any real options beyond microphone and mounting bracket.  I've 
had to learn about Icom interfacing so I could run FSK (AFSK was easy 
via USB).  The '7300 is designed to be an entry level BASIC radio.  And 
that is exactly what I wanted for the RV and holiday style operations.  
The AH-4 allows me to use a grossly non-resonant wire as an antenna; 
much like the Elecraft KX radios (which I didn't choose because I'd have 
to buy an amp too and this was a budget purchase, the AH-4 had a sizable 
rebate).

On FD  the '7300 was grossly overloaded  by others on the air at the 
site.  If I was on 15M and the 20M or 40M station transmitted, the 7300 
front end crumpled with MAJOR desense, ditto when I was on 80M.  My 
inverted Vee (resonant, fed with a twisted pair to the AH-4) was 30' 
from the 20M beam and 120' from the 40M double EDZ (yes I said that 
correctly, it's HUGE, Quad Extended Zepp).  For FD, either a LOT more 
separation or use of another radio is suggested.  I was not able to 
adjust the '7300 enough to ignore the other 100 watt stations without 
making the '7300 deaf.  This was a *planned* worst case scenario (no 
band traps, we've never needed them) specifically for the '7300 and 
similar to previous years of using a 7600, which survived the test.  
This year I will separate my station from the others by a couple hundred 
feet and I expect no issues, except fewer trees and a longer walk to supper.

For use without nearby transmitters, it's been great.  I've used it here 
in the shack to get used to it (Icom is NOT Kenwood or Elecraft, it's 
'different').  For the average home environment, the RV or at 'the 
cabin', it's great.  No issues, sensitive and is all you would expect 
from a current model radio and some nice features (do NOT get the Icom 
software, for $100 it's horrid).

Icom has a history of great radios, crappy microphones for mediocre 
audio.  The stock mic works fine, other Icom mikes I tried, not so 
well.  I use the stock mic and a Heil headset and that works as well.  
If you go Icom, expect you'll have to fuss with mics to get the right 
one (sometimes even the stock mic). Kenwood is famous for their audio 
(Elecraft too, but you opted out of them).

In my research for the '7300 purchase, I found that the output spiking 
issue of the TS-590 line has AT LAST been tamed, BUT each radio must be 
returned for a 'factory' mod.  So if you buy used and EVER plan on using 
an amp, that is something to check.  (That spike was a HUGE reason to 
not get the '590 series when I chose Elecraft, I knew I'd add an amp).

On the other hand, my mobile HF is a Kenwood TS-480HX.  It's not deaf 
but it's also not expected to pick up flea farts in a tornado on the 
road, it's a good solid basic radio with a little more output to 
compensate for the typical lousy mobile antenna (a Tarheel in my case, 
good antenna but mobile is tough).  If I'm not driving and operating, it 
feels like it's on a par with the TS-940 but that empirical not lab 
testing.  Advantage: You can put the control head next to your easy 
chair and hide the radio etc some distance away.

For ragchews, ANY of the above are more than adequate for you use, let 
your budget guide you.  But for a backup rig for working rare DX... THEN 
you have to use Sherwood to help you along.

It was said, the only replacement for a DC-3 was another DC-3.
The same can said for the K3.

I played with a local's 7300 trying to get it hooked up to the computer 
et al.  It only has a USB port.  No band data output.  Make sure your 
logging program supports the 7300, if you do computer logging.

It did put out 100 watts OK.  Adjusting power was a pain. If you have an 
amplifier that needs different drive levels on different bands, this is 
a possible issue.

It is small. I hope you have good strong glasses and tiny fingers. If 
you like menus, you'll love the 7300.  You will need an external speaker.

Not impressed with the spectrum display. Too tiny.

The price (used running $1000-1200) is a real plus.

All the above represents a first impression and there may be ways to 
work around the issues encountered.

The warnings are for connecting SPEAKERS to the Rear Speaker jack. You SHOULD use a TRS plug to lessen the opportunity of the smoke escaping from the speaker stereo amplifier. 

There is no such threat to the Phones jack(s).

Message-ID: <BFEFCEE5-DEE2-408B-9F81-4E8A5F606301@law.du.edu>

A question that?s admittedly a bit OT ? though if I need a pretext, the rig to be used is a K3 . . .

I have been reading through the usual texts about vertical antennas for 80 meters, to replace the half wave dipole I now have and the Vee I had but didn?t like.  But I have not yet found the answer to one question I am thinking about:  The advantages or disadvantages of an inverted L compared to other variations of the top-loaded vertical.

Assume a 40-foot ground-mounted vertical section made with wire running up a fiberglass mast.  There could be a remote tuner or balun at the base if it?s needed.  The top of the vertical section would be guyed with four lines more or less parallel to the earth extending from the top tip of the vertical section to four suitably located trees.  That physical configuration offers three kinds of options.

One is an inverted L.  One of the four guy lines would be a wire making the L and long enough to have the overall antenna resonate, with nonconductive line from there to the tree.  The other three guy lines would be nonconductive for their entire length.

Another would be the classic top-loaded ?T? vertical.  Two opposing guy lines would be equal-length wire out far enough to achieve resonance, with the other two nonconductive for their entire length.

A third would be something closer to a capacity hat.  All four of the guy lines would start at the tip as wires, of equal length and just long enough to effect resonance, with nonconductive rope from there to each of the four trees.  This variation might also have a square loop connecting the distal ends of the four top wires.

If the goal is to have the highest efficiency and the lowest net radiation angle, and if the height of the vertical section is fixed and the radial system is the same for each choice, does it matter which of those three or four options is chosen?  And if it does, how come?

Thanks in advance for any lessons offered . . .

For those who have a DMM with capacitance measuring capabilities, you can measure small caps well enough to separate caps (within a couple of pF) by setting the meter on the bench and running the leads to where you can apply the probes to the capacitor without moving them. Hold the probes near the capacitor and note the reading, then touch the terminals of the cap and note the change. The change is the capacitance of the unit under test. 

That is a neat little kit, Ted. Tnx for the lead.

I went through the same business with my first K2, apparently during the switch-over of trimmer suppliers.  None of the colors matched what they were supposed to be and the errata sheets didn?t help at all.  Don Wilhelm and Gary Surrency both went out of their way to help me sort it out.  

Although my DVM is theoretically able to measure capacitance, the long leads make it essentially useless.  So when I ordered my second K2, while I was waiting for it to arrive I put together a very inexpensive capacitance tester that sold for about $10.  It has PCB mounted test points that work with no leads at all, and the spacing is perfect for these little trimmers.  I then tested what I received in the second K2 kit before mounting them, found that there were still questions, and once again Elecraft came almost instantly to my aid.  But at least I didn?t have to undo anything, or puzzle about why something wasn?t working right.

Sounds as if the K2 trimmer supply is a recurring problem.  Using the capacitance tester before mounting them saved me a great deal of trouble.  Having bought it, I now test EVERY cap before installing.  Takes a while, but it?s reassuring.

There are lots of inexpensive testers available on the ?Net.  I think this is the one I bought:  http://www.nkcelectronics.com/capacitance-meter-kit.html.

    Bob, Don,
    I just finished up a K2 as well.? The trimmers I got didn't match the description in either the manual or errata, so I wasn't sure what I was looking at.
    I had to use clip leads from my cap meter and got too much stray stuff going on to accurately measure min and max.
    I talked to Gary in Watsonville.? Here's what we summized.? The larger bodied yellow trimmers went into c21 and c23.? The remaining 4 smaller bodied white with red band trimmers went into c32, c34, c44 and c46.
    It works.? I get good output on all bands.
    Don't know if this helps or not.

    Bob,
    
    You have too much capacitance at C32 and C34.
    
    Contact Elecraft support and ask them to send 2 trimmer caps to replace 
    C44 and C46.? The ones you have with your kit do not have a small enough 
    minimum capacitance.? The p/n you need is E540011 and the bodies were 
    red the last time I saw them.
    
    The 35 to 70pF range you measured is higher than I would expect.? They 
    should measure about 20pF to 45pF.
    
    If you have a similar problem with the maximum power on 18 MHz as well, 
    ask for replacements for C32 and C34.? The part number is E540002 and 
    they have yellow bodies.
    
    See the latest Errata page - download it from the Elecraft website.
    Trimmer capacitors have become a problem for Elecraft over the past 6 
    months or so.? I believe you have brown body trimmers at C32, C34, C44 
    and C46.? Several of those were found not to meet the manufacturer's 
    specs for capacitance range and were dropped.

Ted,

The inverted L will have some horizontally polarized radiation.  The 
other top loaded verticals should have only vertically polarized 
radiation - assuming that the top loading is symmetrical, whether that 
be a capacity hat or a T wire.

In general, the vertically polarized radiation will be at a lower angle 
than horizontally polarized, but that all depends on the ground 
conductivity and your radial system.  A radial system of 64 radials is 
good if your ground conductivity is decent, but if you are in an area 
where ground conductivity is poor, you may have better luck with 
horizontal antennas or an inverted Vee - the higher the better.

So the answer is "it all depends".  If you do not have a wonderful 
ground screen, a vertical may perform worse than a horizontal antenna 
because a lot of your RF goes into "heating the worms".

Don W3FPR

Ted,

I would recommend very much the site of DJ0IP for tonns of brilliant ideas
on really working antennas. And also a great article of N6LF in QST March,
2010 on radials. You don't need to have 64 or 164 or a chicken mash all
over the field to get the very eficient antenna working DX. 16 is enough.
Based on these excellent sources, I have used myself with great success the
vertical on 80/40 on the 18m Spider mast with the 16 rqdials 12 m long
each. The other time , in the CQWW CW contest, I had no chance to erect the
18m Spider pole due to cold wx condx, so I put up a modernized 43ft
vertical S9 ( a fiberglass pole , actually with the 43 ft of wire inside).
Modernization has come just to adding some 6 more meters of wire to the end
of 43 footter ( making 1/4 waveln. on 80) plus a coax trap and some 20m
more of wire after it ( getting 1/4 waveln. on 160). So I had a Inverted L
with the 14m vertical part and some 26m with a trap horizontal part (
sloping down really to a 4m pole ). The same 16 12m radials stayed due to
lack of time to change them into 25 m each which would be better for 160.
Nevertheless this compromise decision brought me a good 220 qsos on 160m
and around 200 on 80, with barefoot K3 trx incl the Japanese and US
stations on 160m which , for me, was a surprisingly good score. No separate
RX antenna. The resonance was very easy to tune to with the help of the
antenna analyser Youkit FG-01.

It would have been best if I could do this trap combo on a Spider mast with
18m vertical and with 16 radials of 25m long. I will try this this coming
spring, weather permitting.

Wish you good luck and lots of fun with practical experimentation in the
field!

73! Linas LY2H

Verticals are generally an S-unit or maybe 2 noisier on receive than 
horizontal antennas unless you are in a very quiet location.  A base-fed 
1/4 wave [or less] vertical is analogous to a telegraph line with one 
wire, using ground as the return.  If you can't put in a good ground 
system, you'll be disappointed.  I have used Inv-L's and Marconi T's 
with as few as 2 radials on the ground, and they worked, but that's not 
saying much when the alternative was no antenna at all.

Your idea for top loading with the guys will work fine, that's how WWV 
loads their antennas and the way many LORAN-C antennas were loaded.  My 
last 160m inv-L had about 70 ft vertical and the top horizontal was 
about 30 ft which is a bit under 1/4 wavelength. The impedance at the 
bottom was about 57+j130 ohms which matched the 50 ohm coax nicely with 
just a variable cap in series.  I was able to get 12 radials out a few 
inches under the surface.  Worked very good for transmitting, receiving 
... not so much.  It was pretty noisy.

Thanks Bill.  I saw the quote below in Fred's, KE7X, K3s book which caused
me some confusion.  It seems as though he is saying if you use monaural
headphones then you should not set the speakers to 2.  I don't want to give
up AFX or sub audio.

"You may use a monaural headphone set in this jack (which would short the
ring connection to ground) because the 8.2 resistors will protect the
stereo headphone amplifiers. In this case, though, you should set CONFIG:SPKRS
to 1 . You may use CONFIG:SPKR+PH YES to have audio in both the speaker
output and the headphones. "

Yes, but not much, because radiation is the result of current, and 
current is maximum at the bottom and minimum at the far end of the wire. 
And Fred is right on about verticals generally being noisier on RX. But 
not always.

I have a Tee vertical for 160M that works well. 100 ft tall.

Ed, the thing to remember about verticals is that they need an effective 
counterpoise. That can be anything from radials to a screen to a K2AV 
folded counterpoise. AND that verticals are VERY dependent on the 
quality of the soil around you.

There are lots of ideals about this stuff on my website. Study the 
material about getting on 160M, and divide all the dimensions by 2 for 
80M. Then look at my tutorials on verticals vs horizontal antennas. 
k9yc.com/publish.htm  They are written to answer exactly the questions 
you are asking.

My Fluke doesn't measure caps below 100pf, so to test the K2's 12m BPF caps
(including the 1pf), I ended up getting some cheap $15 made-in-China-junk
called a "Honeytek A6013L Capacitor Tester" and assumed I would be
returning it...but I was quite pleasantly surprised at its ability to
pretty reliably measure the 1pf cap. Anyway just another data point...

I own three very nice vintage Ten Tec amps that use vacuum relays. All 
of them came to me used, and I've replaced those relays in each amp at

I have worn out vacuum relays in qsk amps too (replaced only one time in my 12 year-old Alpha 99).  In fact, qsk with vacuum relays is not really qsk in that a vacuum relay is not as fast and silent as what I experienced using Alpha 89, which had switching diodes in it. Alpha 89 to me is the only qsk amp I have used (at ny4a).  You could, in fact, hear been characters at 30 wpm.  

I was disappointed when I purchased my first vacuum relay amp, Alpha 99.  Alpha 99 was defined as qsk but it didn't switch like an Alpha 89.  Seems silly now but since Alpha 99 was defined as "qsk" I expected it to behavior like Alpha 89.   

I even looked around for awhile for an Alpha 89, but then learn how easy it is to blow the diodes in Alpha 89--many owners replaced those expensive diodes, once blown, with vacuum relays.  So, I just decided to run "almost qsk" compared to Alpha 89.

Pin diode rf switches are preferred today.  You can even get the QSK-5 kit from Ameritron if you can't make your own.   Good to 2500 watts and infinite speed.

Subject: [Elecraft] KX3 not receiving anymore
Message-ID: <232D99B7-60D7-4D51-AED8-6B5933008A59@yandex.com>

Hey everyone, I'm trying to get back into digital modes and got out my KX3. 

I have it hooked up to a buddipole antenna, and the tuner is getting a 1:1 swr, but for some reason I'm not hearing or picking up any signals. 

All I'm getting is static. One time on Sunday I picked up a psk exchange between someone here in NC and Cuba, but after that I'm picking up nothing. 

A local ham helped me try and test things, by getting on the same frequency I was (14.070.150) and he was hearing lots of traffic, but I picked up nothing either listening straight through speakers or headphones, or ham radio deluxe using my signalink. 

I get a waterfall, but it's just showing static. 

I wanted to try resetting everything to factory settings, but I can't find any instructions except for how to do it for the K3. 

Does anyone have any ideas on what else I could try or check?

Bill:

Why don't you just get a bare bones used K3. Since it will be a backup 
rig why go and spend the extra $$ for a new rig. By having a second K3, 
you won't have to learn a new rig etc.

I received a load of interesting and solid replies regarding my query 
about the IC-7300. Many were quite technical and some were excellent 
from a daily use perspective. However, without a doubt, the 
non-technical advice regarding a backup rig was the best I received.

" ......... put the money in a savings account and add $50 to cover next 
day shipping for the off chance your rig dies." It was also suggested 
that a second rig is an expensive paperweight (because modern rigs are 
very reliable). "Paperweight" is applicable in my case, as I am only 
able to operate a single rig at a time - I do not do multi-QSO well.

Hence, I have decided on an envelope in the desk labeled "for K3S."   
Better to do that, than to keep a spare on the shelf gathering dust. 
Further, there is no steep learning curve going from a K3 to a K3S.

Thanks to all that replied - I learned a lot.

Theoretically the more top loading you have, the higher the radiation resistance and the better the efficiency. So I like the T better than the L. 
I used to have an open wire fed doublet which could be switched to T configuration. It was very helpful to switch between horizontal and vertical polarization on 80 meters.

I just had to replace one in my TL922 after about 5 years. I'm not a contester, but sometimes I bang away in pileups for a while. I have finally taught myself not to use QSK unless I need it. Setting the delay in the K3 to just enough to keep the relays closed between CW elements is almost as good but saves a lot of operations.
When the pileup is fast enough that I want QSK, it's a button press away.

If that local ham is sufficiently local, why not take your KX3 to his 
location and connect it to his antenna to see if your KX3 is working 
properly.

The Buddipole is not the most efficient antenna and may be the cause of 
not hearing any signals.  The SWR only says it is tuned, but that says 
nothing about its radiation efficiency.

If you want to try resetting to factory defaults, that is in the manual 
(look in the index to find the page).
Be aware that it also resets the calibration data, so be sure you have a 
saved configuration file before doing the EEINIT.  Of course, that saved 
configuration file should be from a time when the KX3 was known to be 
working properly.

Bill,
    I could learn from this wisdom.   Socrates is amongst us.   Some of the
information though was good especially for someone just getting a start.
There are some pretty nice radios out there for low budget not to mention a
used bare bones K3.

What do you want to do with the radio?...for contesting K3/K3s is as good as it gets, so far.  And how was this done?  By improving an already good radio.  I think it is most cool to be able to bring k3 up to K3s performance for about $420 (synthesizer and preamp boards) and not buy a k3s.

K3s ranks second in the Sherwood table--which is based on dynamic range.  However, in a "controlled comparison" between K3s and Flex 6700 (same with the Ic 7300), I suspect K3s would rank number one.  Set all radios to a given and the same MDS and then measure the dynamic range.

Not that dynamic range is the only criterion of a good radio nor the only reason to buy any radio...just saying that this is the criterion used in the Sherwood table of comparison.  And a good criterion if you intend to use the radio in a contest.

I have sat down at a 7300 and it is true that the front end has little
filtering. Additionally, If you have a loud station on CW with in 500hz of
the station you are trying to work, who is weak, the front in will be
de-sensed and the AGC will pump and your QSO will be over. Like most SDR
radios that do not have a Roofing filter ahead of the DSP processing,
selectivity, at best, is questionable. I tuned in to CWOPS CWT contest on
Wednesday evening session and realized that the 7300 is not a CW contest
grade radio. It is too menu deep, big finger unfriendly, for the most part
comparing it to the P3 the band scope on marginal to worthless, and the
less than 500 hertz selectivity for CW is lacking. These observations are
all based on having both the K3S and P3. Although, one thing that the 7300
shines is in its easy computer interfacing to run digital modes. This radio
is a great digital mode radio. If for no other reason, I would buy the 7300
and dedicate it to this mode. But, I don't do digital modes. When packet
radio first came out on HF, it just thought it was the beacon for the
Nation Tune Up Frequency. LOL

My only hope is that the Icom 7610 will address the above issues. When ever
it comes out, maybe Dayton time, that is a radio I want to play with. But
again, most likely it will be in the same dollar level as a K3S P3
combination. For the guy that is starting out in radio, the 7300 offers a
lot of value but learning the controls that are menu hidden rather than
easily adjustable knobs, may not be the best for a new ham to learn on.

My other radios are an Icom 746, Yeasu 450d, yeasu 718, Elecraft K1 4 band
with tuner and of course the K3S with P3 and THP 1.5 running through the
Kat500. Each of these radios has advantages. I am currently putting the
450d into my truck for mobile operation on SSB and to some extent, limited
CW work while mobile.

In the end, each radio has its limitations, but the major limitation is
always money. Buy the best you can afford, put up an efficient antenna and
just have fun. End of Story. The man who dies with the most toys may well
win, but, all the rest of us can still have tons of fun along the way.

Fred,
If your inverted 'L' was a bit less than a quarter wave long, it would have
been capacitive and showing 57-j130  (not plus). In which case you needed a
small inductor to match it to your 50 ohm coax, not a capacitor.

For years with slower keying rigs I would key the amp which would key the
rig. This saved relays. 
When Kenwood came out with the TS-930. 940 etc. they had very nice QSK. But
it was best to use a Mosfet or something to key the amp rather than the
internal rig's relay which was too slow.
I used to key my 2000A then key the rig till I got my first K3. Now I key
the K3 which keys the amp. 

If I am running I do not use QSK. It gives my ears a break. But if I am
hunting and pecking I always use QSK and wish more did also to minimize QRM.

I have no complaints after 17 years of use of the 2000A and only having to
change the vacuum relay once. A very small price to pay for the luxury of
QSK. 
And changing a vacuum relay is usually a lot cheaper than changing the
switching diodes which failed in quite a few Alphas.
Next time you have a vacuum relay fail cut it open to see if the contacts
are burnt from hot switching.

I own three very nice vintage Ten Tec amps that use vacuum relays. All of
them came to me used, and I've replaced those relays in each amp at least
once. After a few rounds of that, I stopped running QSK with those amps. :)
I'd like to hear from others having experience with vacuum relays and QSK at
contesting speeds. I mostly work between 28 and 32 WPM. The original
equipment relays were Jennings, and I've mostly used Gigavac as
replacements. I haven't had to replace one since giving up on QSK about 8
years ago, but I really would like to run QSK. Have I made the right
decision to avoid it when running with a vacuum relay?

I gave up on full QSK several years ago when I started using an active 
receive antenna and a DXE phase controller.  Could not put all that 
stuff inside the keying loop of my Ten Tec Centurion. After the second 
failure of the Centurion QSK board and associated parts, I switched to a 
simple and reliable ACOM 1010 amplifier.

Message-ID: <f524ba5d-dcca-578f-1c76-9acb108683e3@att.net>

Right now, my vintage K3 is back at Elecraft for major upgrades, 
including a second receiver.  I'm enjoying operating the KX2 in the 
meantime.  In fact, it was the dual watch feature of the KX2 that 
clearly demonstrated to me the benefits of a second receiver in working 
the DX pileups.

On Feb. 9, K6JEY wrote:

"I got my KX2 on Thursday (It fills out a pretty big Elecraft "stable"). I got on the ARRL CW DX contest with a dipole and 2 element beam at 25'. I was able to work all continents on 10watts. Europe was the most difficult. I worked a bunch of JA's on 40 at night.  I ended up using one of my Begali paddles with the rig. (I think it weighs more than the radio!) The interface with N1MM was simple and works very well. The receiver is very strong and only got clicks from stations a  hundred hz away.
    Here's what I liked the most. The filter and NB buttons are next to the volume and selectivity knob. And on the left side.  (Probably because I am a leftie) I like the band switch. The peg is perfect  The radio barely got warm all day/night. I tried driving my Ameritron 1306 with it and got 300w output. It helped on a few contacts. Very happy with the radio. Way to go E'craft!
      I like the suggestion of the MFJ whip on 20. Is it better than the Maldol?

Thanks, Jim.  I will get into your tutorials as I continue to absorb and learn from this discussion.

A number of people responded, both on the reflector and directly, with observations similar to yours in at least one important respect ? namely, the quality of the ground really matters to the performance of a vertical.  That factor alone may stop the vertical inquiry in its tracks.  My operating QTH is at 8,600 feet ASL, atop a small mountain ridge dominated by decomposed granite ? about the least conductive soil there is.  The altitude matters because the relative humidity there is very low, the ground vegetation is sparse and so the organic soil is too, and there is no surface water at that elevation save for the snow which as often sublimates away as melts.  In other words, very dry gravel in at least the near field and for much of the land surrounding.   Ah, what I would give to have an ocean nearby again.

Given those conditions, the suggestions seem to be two:  Forget it and put the Vee back up; or do the vertical with a capacity hat and elevated radials.  The latter is possible, as the property has enough space and pine and fir trees despite the harsh growing conditions.   Elevated radials would have to be at least 10 feet high to avoid strangling the deer, not to mention neighbors passing through on their horses. That presents the question of how to get the vertical component of the vertical as long as possible if its base is already ten feet up.   For reasons of domestic tranquility the house itself cannot be an antenna mount.  When I have that construction question solved the discussions about top loading and polarization will be important.

I want also to say thanks to the dozen or so people who offered their knowledge and counsel.  This group is, as always, an extraordinary resource of resourceful friends.

Aren't PIN diodes still a high power 'pipe dream' for ham applications?? Alpha had only limited success with PIN switching, not because the diodes could not switch at high speeds with power, but way too many hams would test their antenna system with bad SWR, or tune their amp into a load with full power output.. While those PIN diodes could withstand the peak forward voltage at 1500 watts of power, very few of them could withstand the peak reverse voltage when the driven load had high SWR! Because most hams are not "careful" when tuning a high power amplifier, Alpha gave up the better PIN diode RF switch approach in favor of 'fast' mechanical relays. 

I used to run QRQ CW speeds in excess of 60/70 wpm (and faster) with outputs of 1500 watts,, but I had to replace my TenTec Titan amp T/R relay annually! (Never could afford an Alpha amp until recently!)

Pin diode rf switches are preferred today.  You can even get the QSK-5 kit from Ameritron if you can't make your own.   Good to 2500 watts and infinite speed.

After a few rounds of that, I stopped running QSK with those amps. :) I'd like to hear from others having experience with vacuum relays and QSK at contesting speeds. I mostly work between 28 and 32 WPM. The original equipment relays were Jennings, and I've mostly used Gigavac as replacements. I haven't had to replace one since giving up on QSK about 8 years ago, but I really would like to run QSK. Have I made the right decision to avoid it when running with a vacuum relay?

Has anyone noted anything "odd" about logging onto QRZ.com today?

It's -very- slow and when I do get on it want's me to load JavaScript.
Have never had to do this.

Please try and see if the site is operating normally, or have they been
hijacked?

BTW, all other sites involving logging it work OK ...

Thanks, and ...

I'm noticing severe delays on some sites, I've now added QRZ to that 
list.  I did not do a traceroute, but I would guess that a major hub is 
offline, so give it a few hours to either come back up or the network 
will readjust.  That takes time to propagate the new paths.

There is a general slowdown on the Internet caused by something with Amazon
Web Services.

I think there is a major Amazon (AWS) cloud computing infrastructure issue
going on today that is causing slow downs with a number of websites. So if
QRZ.com is dependent in any way with that infrastructure they will be
experiencing a slow down. It's impacts a lot of us ...

We continue to experience high error rates with S3 in US-East-1, which is
impacting some other AWS services.

Concurring with Tom, assuming you have the polarity of the X correct, and
there's more.

A short 1/4 wave-ish vertical that shows R=57 in the R+jX expression is a
vertical/counterpoise or radial(s) combo that has far too much resistance
and is a dead giveaway for a considerably inefficient antenna and may be
wasting 3 dB somewhere.

A full quarter wave vertical over 60 1/4 wave radials should be showing
32-35 ohms at resonance, e.g. 33+j0. A theoretical 1/4 wave L in free space
with lossless conductors should be 12-15 ohms. In the real world over real
dirt with an efficient counterpoise, and lacking various possible
real-world inefficiencies an L should be something roughly 25 ohms. Mine is
28 ohms on a calm day over dried out dirt.

Frankly, if it really is efficient, 57-j130 sounds like a fairly *longer*
than 1/4 wave-ish L aerial wire over an FCP without using an isolation
transformer. A bad idea for a stack of reasons.

Otherwise, there is likely a lot of dielectric material inside the bend of
the L adding loss in the R measurement in addition to 32-35 ohms. An
efficient L should show lower R yet to be efficient. Mine is 28 ohms,
measured with an AIM4170 with a calibrated feedline factored out by the
software. An occasional measurement right at the feed is always very close.

In your case R = 57 instead of R = 28 probably means that something like 29
ohms of that 57 is recoverable loss for some reason or other.

It might be related to any sites using S3 that also sell Raspberry Pi's. The 
Pi Zero W was just announced to day so a lot of sites are getting overloaded 
for requests about the new product or by those wanting to buy this latest 
version of the Pi Zero.

So... if I am planning to move to the high desert of New Mexico in a few
years, what is the best low-band antenna option?  I've used verticals over
lots of radials in Massachusetts and Mississippi with good success, but if
I'm up 6500 feet and the water table is WAY down there... what, a dipole?

Subject: [Elecraft] RX Mush, why the fuss?
Message-ID: <063527d3-590c-b508-05ec-4faa8da6514f@triconet.org>

I must confess to some bewilderment about the seemingly endless discussion about 
the adjustment, or mis-adjustment, of AGC slope, threshold or "RF" gain.

Claims are made that one's favorite settings cause signals within the passband 
to retain their relative amplitudes thus allowing the discrimination between 
them, while less favorable settings compress them into "mush."

I will confess that my experience with the design of AGC systems is limited to 
analog receivers and perhaps there is some digital magic that makes DSP radios 
act differently from analog ones in this case.  But in my experience, AGC 
control is derived from the stronger signal received.

After the SNR is adequate (delayed AGC in 1960s terms, above threshold today), 
the overall gain is reduced by some amount to maintain a desired output or to 
prevent overload, and any other signals present suffer the same gain reduction.  
Hence a signal 30 dB stronger than another is still 30 dB stronger even after 
the application of AGC.  If it isn't then we have a very nonlinear receiver, 
which is desirable if we're receiving FM but highly undesirable otherwise.

My reading between the lines suggests that the "mush" proponents think that 
after achieving threshold, changing the slope somehow changes the ratio between 
signals, i.e. there is less gain for strong signals than there is for weaker ones.

Frankly, after 60 years of listening to shortwave noise and in my youth working 
in a machine shop and hanging around too many alcohol and nitro burning race 
cars, my tinnitus practically drives me nuts at times; I welcome a flat AGC slope.

If I'm all wet with this, I'd like to be enlightened.

I too have come to that same surmise, Wes, and I hope whoever explains 
it [someone always does] does so on the reflector so I can benefit too.  
One of my K3's two AGC systems is highly configurable.  I finally found 
a threshold and fairly flat slope that, for my compromised hearing works 
very well.  I operate very little SSB, and I notice nothing I'd call 
"mush" on CW at narrow DSP bandwidths.  If there are multiple signals in 
that BW, the strongest one sets the gain, and all the others respond 
accordingly.

I normally use AGC-F on CW.  Occasionally, with a large difference in 
signal strengths, the gain reduction from the code elements of the 
stronger signal make copy of the weaker signal at a different pitch 
difficult.  AGC-S almost always cures that issue.

Message-ID: <em44536052-9bac-466e-9b5e-c25872920373@jimsdesktop-pc>

I'd like to sell my SDR Play RSP1 SDR monitor receiver. It's barely 
used. Originally sold for $149.95 and currently selling on Ham Radio 
Outlet for $129.95. It normally does not come with the USB A-B cable, 
has an SMA antenna connector and there are a number of different, free, 
downloadable software packages that will run it. The most popular (and 
now being included with it) is SDR Uno. The RSP1 covers 10KHz to 2GHz.  
It's a great monitoring package and with a laptop is also very portable. 
It's powered via the USB cable.

I'll sell this one for $110 shipped anywhere in the US and will include 
a USB A-B cable, an SMA to BNC female antenna adapter and a CD I burned 
containing SDR UNO and the operating manual for it.

Prefer PayPal.

If interested, please reply direct to w0eb at cox.net not via the 
reflector. First "I'll take it" (by date/time of incoming email) will 
get the right to buy it.

Thanks,

Hi Chuck,

In general, with lousy ground, horizontally polarized antennas RULE!  
The earth interacts with verticals in two ways. First, the soil under 
the vertical is a big resistor, burning TX power. Second, where the 
first reflection hits the earth (in the far field) reinforces the direct 
wave to form the vertical pattern. When ground conductivity is poor, 
that reflection is weak.

By contrast, horizontally polarized antennas are only very slightly 
affected by ground losses, and then only almost straight up.

i also have poor soil conductivity (Santa Cruz Mountains). I use 
verticals ONLY on 160M, where even a dipole at 140 ft in my redwoods is 
a low dipole electrically. When I first moved here, I had both. For a 
year or so, I made a lot of A/B comparisons between them, and the 
vertical nearly always won. About five years ago, the horizontal dipole 
came down in a storm, and I didn't even consider putting it back up.

One of my 160 verticals is a Tee with a lot of radials. As an 
experiment, I hung a 67 ft vertical wire over the same radials for 80M. 
My high dipoles blew it away.

In general, horizontal antennas on mountaintops don't need to be very 
high to work really well. I've done FD QRP several times from 
mountaintops using dipoles that were only 25-30 ft off the ground, and 
made QSOs to the midwest and east coast.

Subject: [Elecraft] Elecraft QSK
Message-ID: <7D2C0C73-37B9-4A66-AB8C-0267CB0CA8C4@mac.com>

The Elecraft KPA500 silent QSK is achieved without expensive PIN diodes but rather with relatively inexpensive switching diodes. I?ll guess that the 1500 watt Elecraft prototype amp of some years ago used a similar inexpensive, silent design.

Avoiding QSK should be because of operator preference not because of fear of relay failure. In the case of operating non-QSK, it?s vital for the operator to keep calls short and not be caught in a cycle of doubling with the DX that?s heard all too often.

My Alpha 87A of 17 years or so has never had a PIN diode failure. When the 87A was first introduced there were indeed PIN diode failures. This was attributed to a bad batch (or batches?) of PIN diodes. Subsequent runs of 87A's ceased to exhibit PIN diode failures. Yet the urban legend persists that 87A?s should be avoided because of the PIN diodes - which are expensive to replace.

The real question is why amplifier manufacturers continue to use vacuum relays when inexpensive switching diodes can do the job. Thank you Elecraft.

As per the K60XV Assembly and Operating Instructions Page 18 ?"The IF field can be set to 7, 10, 14, 21, or 28 MHz."
When I go to set the IF the options are only 7, 14, 21, or 28 MHz. ?The 10 MHz option is not available.

I'm running the latest firmware v1.09 on the K2 and v1.02 on the K60XV ? (or so I would believe it to be as this is a new K2).

Can anyone check to see if they have 10 MHz as an IF option on their K2.

Thank you

My thoughts on this are that those who are concerned about the slope 
and threshold settings are barking up the wrong tree. The mush would 
result if you have your hold time or hang time or decay set too short. 
With a brief hold time the weaker signal pops up to the level of the 
stronger on as soon as the stronger one disappears. A longer hold time 
keeps the relative level of the two signals at the correct 
relationship. The answer is hold time, not threshold or slope.

Those of us in the southeastern US may have a problem with all the 
lighting we get. The lightning spikes tend to drive the desired signal 
too low. So we kinda have to keep hold time short if we are to hear 
anything. But there should be some level of decent compromise in there 
somewhere. IIRC the K3 has an AGC setting that helps with this but 
does not eliminate it.

I am not certain what it has to do with "mush", but it does seem to help.

What is certain is that if the AGC Threshold is set too low, the AGC 
will be activated on band noise.  Whether that 'band noise' is the 
result of ambient noise level, or the ambient 'noise' of a multitude of 
signals in close frequency proximity is for the user to determine.

As far as the slope is concerned, yes, the AGC will respond to the 
strongest signal in the passband, that is a fact.
The reason for setting the slope to something other than flat is not a 
consideration for reducing the RX Mush, but it allows the user to 
evaluate by ear the relative strength of signals.

In summary, signals below the threshold will be received the same as 
with the AGC off.  Signals above the threshold will be reduced according 
to the slope of the AGC response, but the strongest one in the passband 
will take control of the AGC.

It is nice to be able to report an S6 signal is weaker than an S8 or S9 
signal without depending on the S-meter.  Of course, all signals in a 
contest or for reports to a DX station are always 59 or 599.

I am unable to select 10 Mhz for an IF for transverter use only selections are 7,14,21, or 28

10 Mhz is enabled (can you disable a band on the K2) and works as a regular band.

Subject: [Elecraft] KX3 & CQ-160
Message-ID: <00de01d29240$17659060$4630b120$@arrl.net>

Just thought I'd drop a note on my experience using my KX3/PX3 setup for the
CQ-160 contest this past weekend.

 

I operated this contest last year using a 100W radio but decided to try QRP
this year.  I'm fortunate to be able to use an insulated AM broadcast tower
(220' w/120 ground radials) and had a very nice experience last year (2016).
So, thought I'd try QRP with my KX3 this year (2017).  My setup is a small
table in front of the AM tower's ATU connected to the tower side of a blank
J-Plug inserted into the jack (electrically disconnects the AM tuning unit
from the tower - and yes, the AM station was QRT during this time) using the
dual banana adapter on the KX3 with short leads going to ATU ground and the
tower side J-plug terminal.  The KXAT3 had no problem tuning the antenna
(tower) for 160m.

 

First off, the KX3's receiver was fabulous - this is the first time I've
used my KX3 during such crowded conditions and also with such a good antenna
where signals were strong.  It handled the conditions very well.  I found
operating with the RF gain at -30 made listening more comfortable.  However,
the KX3's receiver did not seem to have any problems prior to me reducing
the RX gain.  The PX3 was certainly nice to be able to "see" the band.
Unfortunately, being QRP I wasn't able to make nearly the Q's that I did
last year due to some stations just not being able to pull me out (many were
saying they had high noise or QRM).   I'm sure CW and/or the digital modes
would've been a bit more effective with this setup.  It seemed having the
stereo effect enabled on the KX3 resulted in a lot less ear fatigue using
earbuds.  I was able to make many contacts for the limited time (4 hrs.)
that I was operating.

 

Since I don't recall seeing much discussion using the KX3 on 160m with an
efficient antenna I thought I'd share my experience.  So, for those that
might be into the broadcast engineering circles and have access to an AM
tower (or other type of efficient 160m antenna) I'd certainly recommend
using a KX3 with such an antenna.

Richard

One characteristic of a "T", assuming the top wires run in opposite directions and are of equal length, is that radiation from the top wires is highly suppressed because they are fed "in phase" by the vertical section. That means that nearly all radiation is from the vertical section, whereas in an inverted "L" arrangement there is considerable radiation from the horizontal section.

Some ultimate "T" type antennas for H.F. were the very short verticals documented by Jerry Severt (W2FMI, SK) using umbrella-like multiple top hat loading with many "spokes". The QST archives have his articles.

Theoretically the more top loading you have, the higher the radiation resistance and the better the efficiency. So I like the T better than the L. 
I used to have an open wire fed doublet which could be switched to T configuration. It was very helpful to switch between horizontal and vertical polarization on 80 meters.

73, Jim K9YC
-----------------------------------------------------------------------
Hi Gents,

The "secrete" to running QSK with an amplifier is proper sequencing
of whatever keying is used...relays or PINs.

I still have, and use, my old Alpha 86 which uses PIN diodes, but
it is set up to be keyed *first*.  When the Alpha is ready to transmit, 
*then* the keying signal is passed on to my K3 or whatever radio
I have connected to it.  If I just key a radio first, without the
amplifier being set up, the amp will "trip out" and announce
that it had a "T-R" fault.  

Keying a radio ("exciter"), then keying a amp, will cause
hot-switching unless there is a built-in delay of RF from the radio.
